Patent ID: 8264649

Claim:
A liquid crystal device comprising: a pair of substrates, liquid crystal sandwiched between the pair of substrates, a plurality of sub-pixels, each sub-pixel having a transmissive display region and a reflective display region; a color filter disposed on the one of the substrates; a transparent insulating film disposed between the liquid crystal and the color filter and being provided in the transmissive display region and the reflective display region, so as to define a first layer thickness of the liquid crystal in the reflective display region and a second layer thickness of the liquid crystal in the transmissive display region, the first layer thickness being smaller than the second layer thickness, the transparent insulating film including: a first thin-walled portion provided in the transmissive display region; a second thin-walled portion that is thicker than the first thin-walled portion, the second thin-walled portion provided in the reflective display region in a region along a boundary between the adjacent sub-pixels; and a surface groove formed in the transparent insulating film disposed in the reflective display region, the surface groove having a depth in the range of 30% to 90% of a thickness of the transparent insulating film for improving alignment of the liquid crystal, the surface groove being provided in the region along the boundary between the adjacent sub-pixels of the second thin-walled portion, the surface groove arranged corresponding to a period of plural sub-pixels; and an orientation film disposed on the transparent insulating film and within the surface groove.
