`
`ABSTRACT
`
`The invention relates to a liquid crystal display based on an
`MVA mode of multi-division alignment in which alignment
`states of liquid crystal molecules having a negative dielectric
`anisotropy are made different from each other, and provides
`a liquid crystal display in which a drop in transmittance is
`suppressed and response characteristics are improved. The
`liquid crystal display is constructed so as to include a pair of
`substrates having a predetermined cell gap and arranged
`opposite to each other, vertical alignment films formed
`between the pair of substrates, a liquid crystal layer sealed
`between the vertical alignment films and having a negative
`dielectric anisotropy, an alignment regulating structural
`member arranged on at least one of the pair of substrates, for
`regulating a total alignment direction of liquid crystal mol-
`ecules in the liquid crystal
`layer at a time of voltage
`application, and a cured material provided in the liquid
`crystal
`layer and including a liquid crystal skeleton for
`tilting the liquid crystal molecules.

`LIQUID CRYSTAL DISPLAY
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to a liquid crystal display
`(LCD), and particularly to a liquid crystal display based on
`an MVA (Multi-domain Vertical Alignment) mode of multi-
`division alignment
`in which alignment states of liquid
`crystal molecules having a negative dielectric anisotropy are
`made different from each other.
`
`2. Description of the Related Art
`An LCD is regarded as the most promising substitute for
`a CRT among various flat panel displays. It is expected that
`the LCD has an extended market by being applied to not
`only a display monitor of a PC (Personal Computer), a word
`processor, or an OA equipment, but also a display portion of
`a consumer (household electric) appliance such as a large
`screen television or a portable small-sized television.
`A display operation mode of the LCD, which is most
`frequently used at present, is a normally-white mode using
`a TN (Twisted Nematic) liquid crystal. This LCD includes
`electrodes respectively formed on opposite surfaces of two
`glass substrates arranged opposite to each other, and hori-
`zontal alignment films formed on both the electrodes. The
`two horizontal alignment films are subjected to an alignment
`processing by rubbing or the like in the directions perpen-
`dicular to each other. Besides, polarizing plates having
`polarization axes adjusted to be parallel
`to the rubbing
`directions of the alignment films of the inner surfaces of the
`substrates are respectively arranged at the respective outer
`surfaces of the substrates.
`
`When a nematic liquid crystal having a positive dielectric
`anisotropy is sealed between the substrates, liquid crystal
`molecules in contact with the alignment film are aligned in
`the rubbing direction. That is, the alignment directions of the
`liquid crystal molecules being in contact with the two
`alignment films cross at right angles. At the same time as
`that, the liquid crystal molecules between both the substrates
`are lined up in the direction vertical to the substrate surface
`while the alignment direction is successively rotated in a
`plane parallel to the substrate surface, and the liquid crystal
`is twisted with a twist angle of 90° between the substrates
`and is lined up.
`If light is made incident on one of the substrate surfaces
`of the TN type LCD of the above construction, when linearly
`polarized light having passed through the polarizing plate at
`the side of the one substrate passes through the liquid crystal
`layer, the polarization orientation rotates in an arc of 90°
`along the twist of the liquid crystal molecules, and the light
`passes through the polarizing plate at the side of the other
`substrate having the polarization axis orthogonal
`to the
`polarizing plate at the side of the one substrate. By this, a
`bright state display can be obtained at the time of no voltage
`application (normally-white mode).
`When a voltage is applied between the opposite
`electrodes, since major axes of the nematic liquid crystal
`molecules having the positive dielectric anisotropy are
`aligned perpendicularly to the substrate surface, the twist
`disappears. The liquid crystal molecules do not have bire-
`fringence (refractive index anisotropy) relative to the lin-
`early polarized light incident on the liquid crystal layer of
`this state. Accordingly, since the incident light does not
`change its polarization direction, it can not pass through the
`other polarizing plate. By this, a dark state display is

`obtained at the time of predetermined maximum voltage
`application. When the state is again made the no voltage
`application state, it is possible to return the display to the
`bright state display by alignment regulating force. Besides,
`a gradation display becomes possible by changing the
`applied voltage to control
`the tilt of the liquid crystal
`molecule and to change the intensity of transmitted light
`from the other polarizing plate.
`An active matrix TN type TFT-LCD in which a TFT (Thin
`Film Transistor) is provided in each pixel as a switching
`element for controlling an applied voltage between opposite
`electrodes for each pixel is widely used for a PC display
`monitor, a portable television or the like since it is thin and
`lightweight, and a large screen and high quality can be
`obtained. A manufacturing technique of the TN type TFT-
`LCD is remarkably advanced in recent years, and the
`contrast, color reproduction property and the like when
`looking at the screen front ways are superior to a CRT.
`However, the TN type TFT-LCD has a fatal defect that a
`viewing angle is narrow. Especially, the viewing angle in the
`vertical direction is narrow in panel observation directions.
`The luminance of a dark state increases in one direction and
`
`an image becomes whitish, and a dark display is obtained as
`a whole in the other direction, and a luminance inversion
`phenomenon of an image occurs at a halftone. This is the
`biggest defect of the TN type LCD.
`As an LCD which has solved the problem of the viewing
`angle characteristics of the TN type LCD,
`there is an
`MVA-LCD disclosed in Japanese Patent No. 2947350. An
`example of the construction of the MVA-LCD will be
`described. First, electrodes are respectively formed at the
`sides of opposite surfaces of two substrates having a pre-
`determined gap and arranged opposite to each other. Vertical
`alignment films are formed on both the electrodes, and a
`liquid crystal having a negative dielectric anisotropy is
`sealed between the two vertical alignment films. Aplurality
`of linear projections made of insulators are periodically
`formed between the electrodes and the vertical alignment
`films of both the substrates. The linear projections opposite
`to each other between the two substrates are arranged while
`they are shifted by a half pitch from each other when viewed
`from the substrate surface. The linear projections are used
`for alignment control to divide the liquid crystal in a pixel
`region into plural alignment orientations. Incidentally, even
`if slit portions are provided on the electrodes instead of the
`linear projections, the alignment division can be controlled.
`Two polarizing plates having polarization axes orthogonal
`to each other are provided at the outer surfaces of the two
`substrates. The attachment directions of the polarizing plates
`are adjusted so that the orientations of the major axes of the
`liquid crystal molecules tilted on the substrate display sur-
`faces at the time of voltage application become approxi-
`mately 45° with respect
`to the polarization axes of the
`polarizing plates when viewed from the substrate surface.
`When a nematic liquid crystal having a negative dielectric
`anisotropy is sealed between the substrates, the major axes
`of the liquid crystal molecules are aligned in the vertical
`direction with respect to the film surface of the vertical
`orientation film. Thus, the liquid crystal molecules on the
`substrate surface are aligned vertically to the substrate
`surface, and the liquid crystal molecules on the tilted sur-
`faces of the linear projections are aligned obliquely to the
`substrate surface.
`
`is made incident on one of the substrate
`When light
`surfaces in the state where a voltage is not applied between
`both the electrodes of the MVA-LCD of the above

`the linearly polarized light having passed
`construction,
`through the one polarizing plate and incident on the liquid
`crystal layer travels in the directions of the major axes of the
`vertically aligned liquid crystal molecules. Since birefrin-
`gence does not occur in the directions of the major axes of
`the liquid crystal molecules, the incident light travels with-
`out changing the polarization orientation, and is absorbed by
`the other polarizing plate having the polarization axis
`orthogonal to that of the one polarizing plate. By this, a dark
`state display is obtained at the time of no voltage application
`(normally-black mode).
`When a voltage is applied between the opposite
`electrodes, the major axes of the liquid crystal molecules are
`aligned parallel to the substrate surface while the alignment
`orientations of the liquid crystal molecules on the substrate
`surface are regulated in accordance with the alignment
`orientations of the liquid crystal molecules tilted by the
`linear projections in advance.
`The liquid crystal molecule has birefringence relative to
`the linearly polarized light incident on the liquid crystal
`layer of this state, and the polarization state of the incident
`light is changed according to the tilt of the liquid crystal
`molecule. At the time of predetermined maximum voltage
`application, since the light passing through the liquid crystal
`layer becomes, for example, linearly polarized light in which
`the polarization orientation rotates in an arc of 90°, it passes
`through the other polarizing plate and a bright state display
`is obtained. When the state of no voltage application is again
`produced,
`the display can be returned to the dark state
`display by the alignment regulating force. Besides, a gra-
`dation display becomes possible by changing the applied
`voltage to control the tilt of the liquid crystal molecule and
`to change the intensity of transmitted light from the other
`polarizing plate.
`According to the active matrix MVA system TFT-LCD in
`which a TFT is formed in each pixel, since the alignment
`orientation of the liquid crystal in the pixel can be divided
`into plural ones, as compared with the TN type TFT-LCD,
`an extremely wide viewing angle and high contrast can be
`realized. Besides, since a rubbing processing is not required,
`the manufacturing process becomes easy and the manufac-
`turing yield can be improved.
`However, the conventional MVA system TFT-LCD can be
`improved in the response time of a display. That is, a high
`speed response can be made in the case where black is again
`displayed after a black display was changed to a white
`display. However, a response time when a halftone is
`displayed from another halftone is rather inferior to the TN
`type TFT-LCD.
`Besides, also with respect to the transmittance of light,
`although the conventional MVA system TFT-LCD is sub-
`stantially twice as excellent as a wide viewing angle LCD of
`an IPS (In-plane Switching) system of a horizontal electric
`field system, it is inferior to the TN type TFT-LCD.
`As stated above, although the MVA system TFT-LCD has
`solved the problem of the conventional LCD with respect to
`the viewing angle, contrast, and response time of black-
`white-black display, it does not exceed the conventional TN
`type LCD with respect to the response time at a halftone
`display and the transmitta
