`ABSTRACT
`(57)
`A transparent light emitting diode (LED) includes a plurality
`of III-nitride layers, including an active region that emits
`light, wherein all of the layers except for the active region
`are transparent for an emission wavelength of the light, such
`that the light is extracted effectively through all of the layers
`and in multiple directions through the layers. Moreover, the
`surface of one or more of the III-nitride layers may be
`roughened, textured, patterned or shaped to enhance light
`extraction.
