`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to a MVA (Multi-domain
`Vertical Alignment) mode liquid crystal display device, and
`particularly to a liquid crystal display device in which a
`polymer for determining a direction in which liquid crystal
`molecules tilt while voltage is being applied is formed in a
`liquid crystal layer thereof.
`2. Description of the Prior Art
`In general, a liquid crystal display device is constituted of:
`a liquid crystal panel which is fabricated to contain liquid
`crystal between two substrates thereof; and polarizing plates
`which are arranged respectively in the two sides of the liquid
`crystal panel. A picture element electrode is formed in each of
`picture elements in one substrate ofthe liquid crystal panel. A
`common electrode used commonly for the picture elements is
`formed in the other substrate ofthe liquid crystal panel. When
`voltage is applied between the picture element electrode and
`the common electrode, alignment directions of liquid crystal
`molecules change depending on the voltage. As a result, this
`changes an amount of light which passes the liquid crystal
`panel and the polarizing plates arranged respectively on the
`two sides of the liquid crystal panel. If applied voltage were
`controlled for each of the picture elements, a desired image
`can be displayed on the liquid crystal display device.
`With regard to a TN (Twisted Nematic) mode liquid crystal
`display device which has been heretofore used widely, liquid
`crystal with positive dielectric anisotropy is used, and liquid
`crystal molecule is twisted and aligned between the two sub-
`strates. However, the TN mode liquid crystal display device
`has a disadvantage of having insufiicient viewing angle char-
`acteristics. In other words, with regard to the TN mode liquid
`crystal display device, tone and contrast are extremely dete-
`riorated when the liquid crystal panel is viewed in an oblique
`direction. Accordingly, the contrast is reversed in extreme
`cases.
`
`An IPS (In-Plane Switching) mode liquid crystal display
`device and a MVA (Multi-domain Vertical Alignment) mode
`liquid crystal display device have been known as liquid crys-
`tal display devices having goodviewing angle characteristics.
`With regard to the IPS mode liquid crystal display device,
`picture element electrodes shaped like a line and common
`electrodes shaped like a line are arranged alternately in one of
`the two substrates. Ifvoltage were applied between one of the
`picture element electrodes and neighboring one of the com-
`mon electrodes, the orientations respectively of the liquid
`crystal molecules change in a plane parallel with a surface of
`the substrate depending on the voltage.
`Although, however, the IPS mode liquid crystal display
`device is good at viewing angle characteristics, the orienta-

`
`tions respectively of the liquid crystal molecules above the
`picture element electrode and the common electrode cannot
`be controlled since voltage is applied in a direction which is
`parallel with the substrate. This brings about a disadvantage
`that the IPS mode liquid crystal display device substantially
`has a low aperture ratio, and that the screen of it is dark if a
`powerful backlight were not used.
`With regard to the MVA mode liquid crystal display device,
`picture element electrodes are formed in one of the two sub-
`strates, and a common electrode is formed in the other of the
`two substrates. In addition, with regard to a generally-used
`MVA mode liquid crystal display device, bank-shaped pro-
`trusions made of dielectric material extending in an oblique
`direction are formed on the common electrode. Each of the
`
`picture element electrodes is provided with slits parallel with
`the protrusions.
`With regard to the MVA mode liquid crystal display device,
`while voltage is not being applied, the liquid crystal mol-
`ecules are aligned in a direction perpendicular to the sub-
`strates. When voltage is applied between each of the picture
`element electrodes and the corresponding common electrode,
`the liquid crystal molecules are aligned to tilt at an angle
`corresponding to the voltage. In this occasion, a plurality of
`domains are formed in each ofthe picture elements by the slits
`provided into the picture element electrode and by the corre-
`sponding bank-shaped protrusions. The directions in which
`the liquid crystal molecules tilt vary from one domain to
`another. Ifthe plurality of domains were formed in any one of
`the picture elements while the directions in which the liquid
`crystal molecules tilt vary from one domain to another, good
`viewing angle characteristics can be obtained.
`With regard to the aforementioned MVA mode liquid crys-
`tal display device, the slits and the protrusions decrease the
`substantial aperture ratio. Accordingly, the substantial aper-
`ture ratio of the MVA mode liquid crystal display device is
`lower than that of the TN mode liquid crystal display device,
`although the substantial aperture ratio is not so low as that of
`the IPS mode liquid crystal display device. For this reason,
`the MVA mode liquid crystal display device needs a powerful
`backlight. As a result, this kind of MVA mode liquid crystal
`display device has hardly been adopted for a notebook per-
`sonal computer, which requires power consumption to be low.
`Japanese Patent Laid-open Official Gazette No. 2003-
`149647 has disclosed a MVA mode liquid crystal display
`device which was developed in order to solve the aforemen-
`tioned problems. FIG. 1 is a plan view showing the MVA
`mode liquid crystal display device. Incidentally, FIG. 1 shows
`two picture element regions.
`A plurality of gate bus lines 11 extending in the horizontal
`direction Oi-axis direction) and a plurality ofdata bus lines 12
`extending in the vertical direction (Y-axis direction) are
`formed on one of the two substrates constituting a liquid
`crystal panel. An insulating film (gate insulating film) is
`formed in each ofthe rectangular areas defined by the gate bus
`lines 11 and the data bus lines 12. This formation electrically
`isolates the gate bus lines 11 from the data bus lines 12. Each
`of the rectangular areas defined by the gate bus lines 11 and
`the data bus lines 12 is a picture element region.
`A TFT (thin film transistor) 14 and a picture element elec-
`trode 15 are formed in each of the picture element region. As
`shown in FIG. 1, the TFT 14 uses part ofthe gate bus line 11
`so as to cause the part to function as a gate electrode. A
`semiconductor film (not illustrated) which functions as an
`active layer of the TFT 14 is formed above the gate electrode.
`A drain electrode 14a and a source electrode 14b are con-
`
`nected respectively to the two sides of this semiconductor
`film in the Y-axis direction. The source electrode 14b of the

`TFT 14 is electrically connected to the data bus line 12, and
`the drain electrode 14a is electrically connected to the picture
`element electrode 15.
`
`In this patent application, out of the two electrodes con-
`nected to the semiconductor film which functions as the
`
`active layer of the TFT, one electrode to be connected to the
`data bus line is termed as a source electrode, and the other
`electrode to be connected to the picture element electrode is
`termed as a drain electrode.
`
`The picture element electrode 15 is formed of a transparent
`conductive material such as ITO (Indium-Tin Oxide). Slits
`1511 are formed in this picture element electrode 15 in order to
`cause liquid crystal molecules to be aligned in one of four
`directions when voltage is applied. In other words, the picture
`element electrode 15 is divided into four domains with the
`
`center line in parallel with the X-axis direction and the center
`line in parallel with the Y-axis direction defined as bound-
`aries. A plurality of slits 15a extending in a direction at an
`angle of 45 degrees to the X axis are formed in a first domain
`(upper right domain). A plurality of slits 15a extending in a
`direction at an angle of 135 degrees to the X axis are formed
`in a second domain (upper left domain). A plurality of slits
`15a extending in a direction at an angle of 225 degrees to the
`X axis are formed in a third domain (lower left domain). A
`plurality of slits 15a extending in a direction at an angle of3 l 5
`degrees to the X axis are formed in a fourth domain (lower
`right domain). A vertical alignment film (not illustrated)
`made ofpolyimide is formed on the picture element electrode
`15.
`Black matrices, color filters and a common electrode are
`formed in the other substrate. The black matrices are made of
`
`a metal such as Cr (chromium), or of black resin. The black
`matrices are arranged respectively in positions, each ofwhich
`is opposite to any one of the gate bus lines 11, the data bus
`lines 12 and the TFTs 14. The color filters are classified into
`
`three types, such as red, green and blue. Any one of the three
`types of color filters is arranged in each of the picture ele-
`ments. The common electrode is made of a transparent con-
`ductive material such as ITO, and is formed on the color
`filters. A vertical alignment film made ofpolyimide is formed
`on the common electrode.
`
`A liquid crystal panel is constituted in the following man-
`ner. These substrates are arranged to be opposite to each other
`with spacers (not illustrated) interposed between the two
`substrates. Liquid crystal with negative dielectric anisotropy
`is filled between the two substrates. Hereinafter, out of the
`two substrates constituting the liquid crystal panel, one sub-
`strate on which a TFT is formed will be termed as a TFT

`substrate, and the other substrate which is arranged to be
`opposite to the TFT substrate will be termed as an opposing
`substrate.
`
`50
`
`In the case of the MVA mode liquid crystal display device
`shown in FIG. 1, the liquid crystal molecules are aligned
`virtually perpendicularly to the surface of each of the sub-
`strates while voltage is not being applied to the picture ele-
`ment electrode 15. When voltage is applied to the picture
`element electrode 15, the liquid crystal molecules 10 tilt in the
`directions in which the respective slits 15a extend as sche-
`matically shown in FIG. 1. Accordingly, four domains are
`formed in any of the picture elements while the directions in
`which the liquid crystal molecules tilt vary from one domain
`to another. This inhibits light from leaking in oblique direc-
`tions, and thus securing good viewing angle characteristics.
`Changing the subject. In the case of the MVA mode liquid
`crystal display device shown in FIG. 1,
`it remains to be
`determined whether the liquid crystal molecules 10 tilt
`inwards (in directions of the center of the picture element) or
`
`55
`
`60
`
`65
`
`4
`
`outwards (in directions ofthe outside of the picture element),
`immediately after voltage is applied to the picture element
`electrode 15. First of all, the electric field in extremities ofthe
`picture element electrode 15 determines the liquid crystal
`molecules 10 in extremities of the slits 1511 (near the data bus
`line 12) to tilt inwards. Subsequently, the liquid crystal mol-
`ecules 10 in positions inwards from the extremities tilt
`towards the center of the picture element. Then, the liquid
`crystal molecules 10 in positions further inwards from the
`extremities tilt towards the center ofthe picture element. This
`process is repeated until all the liquid crystal molecules tilt
`towards the center of the picture element. Accordingly, it
`takes time for all the liquid crystal molecules 10 in a picture
`element to complete tilting in predetermined directions. This
`brings about a problem that the response time is long.
`The aforementioned Japanese Patent Laid-open Official
`Gazette No. 2003-149647 has disclosed that a liquid crystal
`display device is fabricated in the following manner. First,
`liquid crystal to which a polymer component (monomer) is
`added is filled into the space between the pair of the sub-
`strates. Then, voltage is applied between the picture element
`electrode and the common electrode, thereby causing the
`liquid crystal to align in predetermined directions. Thereafter,
`beams of ultraviolet light are irradiated to the polymer com-
`ponent, and thereby the polymer component is polymerized.
`By this, polymer is made in the liquid crystal layer. In the case
`of the liquid crystal display device thus fabricated, the poly-
`mer in the liquid crystal layer determines directions in which
`the liquid crystal molecules tilt. For this reason, no sooner is
`voltage applied between the picture element electrode and the
`common electrode than all of the liquid crystal molecules in
`the picture element start to tilt in predetermined directions.
`Accordingly, the response time is reduced to a large extent.
`In addition, addition of a polymer component to liquid
`crystal has been disclosed, also, by Japanese Patent Laid-
`open Official Gazette No. Hei. 11-95221 and Japanese Patent
`Laid-open Official Gazette No. Hei. 8-36186.
`In general, in the case of a vertical alignment (VA) mode
`liquid crystal display device, it has been known that the gray-
`scale brightness characteristics to be observed when the liq-
`uid crystal display device is viewed from the front is different
`from that to be observed when the liquid crystal display
`device is viewed in an oblique direction. The aforementioned
`MVA mode liquid crystal display device also has the same
`defect. FIG. 2 is a diagram showing a gray-scale brightness
`characteristics to be observed when the MVA mode liquid
`crystal display device is viewed from the front, and a gray-
`scale brightness characteristics to be observed when the MVA
`mode liquid crystal display device is viewed in a direction at
