Patent ID: 8421968

Claim:
A liquid crystal display apparatus wherein a transmission region and a reflection region are disposed in parallel, comprising: a first substrate; a flattening film carried on said first substrate; a second substrate; a liquid crystal layer disposed between said first and second substrates; a pixel electrode carried on said second substrate; a counter electrode; an interlayer insulating film between said liquid crystal layer and said counter electrode, said interlayer insulating film including (a) a first insulating film of thickness t 1 in said transmission region and (b) a second insulating film in said reflection region of thickness t 2 ; and a reflecting film in the reflection region and between said counter electrode and said interlayer insulating film; wherein, a portion of said counter electrode in said transmission region has a same film thickness as a portion of said counter electrode in said reflection region, said first insulating film is in contact with said counter electrode in the transmission region while said second insulating film is in contact with said reflecting film in the reflection region, said counter electrode, said interlayer insulating film, and said pixel electrode are configured to form a fringe field for driving molecules of the liquid crystal, t 1 and t 2 are such that driving voltages for said transmission region and said reflection region can be substantially equal to each other, the thickness t 1 of said first insulating film is uniform over a region extending over said entire counter electrode in said transmission region, and the flattening film is provided in said reflection region of said first substrate to adjust a gap between said first and second substrates and create a difference in a thickness of the liquid crystal layer in said reflection region that is less than a thickness of the liquid crystal layer in said transmission region.
