Patent ID: 7646454

Claim:
A transflective liquid crystal display device, comprising: a front substrate on a viewer side, and a rear substrate; a liquid crystalline cell sandwiched between the front substrate and the rear substrate, said liquid crystalline cell having transmissive portions for selectively passing light generated by a backlight, and reflective portions for selectively reflecting ambient light said transmissive portions provided with a first cell gap and said reflective portions provided with a second cell gap, an optical retarder at the viewer side of said liquid crystalline cell, a thickness of said optical retarder being such as to compensate a difference between the first cell gap and the second cell gap; and a color filter having a different thickness for the reflective portions and the transmissive portions of the cell, wherein the thickness of the optical retarder is such as to compensate both a difference between the first cell gap and the second cell gap, and said different thickness of said color filter.
