Patent ID: 7064802

Claim:
A pixel device of a transflective-type LCD, comprising: an upper panel; a lower panel, located under said upper panel, having an upper surface separated into a reflective region covered with a reflector and a transmission region; a hybrid-type nematic LC layer, interposed between said upper panel and said lower panel; a first pixel electrode and a first common electrode, formed separately on said reflective region, spaced by a first interval to form a lateral electric field for driving said hybrid-type nematic LC layer; and a second pixel electrode and a second common electrode, formed separately on said transmission region, spaced by a second interval to form another lateral electric field for driving said hybrid-type nematic LC layer, and said first interval being larger than said second interval; wherein, while an operating voltage is applied to said pixel device, a smaller retardation is formed in said hybrid-type nematic LC layer of said reflective region with respect to that of said transmission region.
