Patent ID: 7015996

Claim:
A liquid crystal display device, comprising: a first substrate; a plurality of pixel electrodes formed on said first substrate, each of said pixel electrodes including a reflective region and a transmissive region; a first insulation film interposed between said reflective region and said first substrate; a second substrate disposed in opposition to said first substrate; a first color layer formed on said second substrate and disposed at a location corresponding to said reflective region; a second color layer formed on said second substrate and disposed at a location corresponding to said transmissive region; a common electrode covering said first color layer and said second color layer; and a liquid crystal layer interposed between said first substrate and said second substrate, wherein the thickness of said liquid crystal layer at the location corresponding to said reflective region and the thickness of said liquid crystal layer at the location corresponding to said transmissive region are equal when said liquid crystal layer has a twist angle of 72 degrees, and as said twist angle decreases from 72 degrees to 0 degrees, the difference between said thickness of said liquid crystal layer at said location corresponding to said reflective region and said thickness of said liquid crystal layer at said location corresponding to said transmissive region increases until said thickness of said liquid crystal layer at said location corresponding to said reflective region becomes substantially one-half said thickness of said liquid crystal layer at said location corresponding to said transmissive region when said twist angle=0.
