Claim:
A method for manufacturing a liquid crystal display device, comprising: forming a plurality of wiring lines intersecting one another and wired longitudinally and laterally on a first substrate while partitioning a display area into a plurality of pixels on said first substrate; forming on said first substrate a first insulation film covering said plurality of wiring lines and said plurality of pixels; defining in each of said plurality of pixels a reflective region for reflecting light from a display face and a transmissive region for allowing light from a back light positioned opposite said plurality of pixels with reference to said first substrate, and then, forming an insulation film for reflection corresponding to said reflective region on said first insulation film; forming a reflective electrode on said insulation film for reflection; forming on said first insulation film a transparent electrode corresponding to said transmissive region; forming on a second substrate a color layer for reflection and a color layer for transmission so as to correspond to said reflective region and said transmissive region, respectively; forming a common electrode so as to cover said color layer for reflection and said color layer for transmission; disposing said second substrate in opposition to said first substrate; and interposing a liquid crystal layer between said first substrate and said second substrate, wherein a thickness of said liquid crystal layer corresponding to said reflective region is different than a thickness of said liquid crystal layer corresponding to said transmissive region, wherein a thickness of a portion of said liquid crystal layer interposed between a surface of said reflective electrode and a surface of said color layer for reflection and a thickness of a portion of said liquid crystal layer interposed between a surface of said transparent electrode and a surface of said color layer for transmission are configured to maximize a reflectance in said reflective region and a transmittance in said transmissive region with respect to individual twist angles of liquid crystal molecules, and wherein a boundary between said color layer for reflection and said color layer for transmission is unaligned with a boundary between said reflective and transmissive regions.
