Patent ID: 7755723

Claim:
A liquid crystal display device comprising: a liquid crystal layer sandwiched between a first substrate and a second substrate; a reflective display area including, between said first and second substrates, (1) a common electrode and (2) a pixel electrode having a plurality of slits so as to apply an electric field to the liquid crystal layer; and between the first substrate and the pixel electrode, an interlayer insulating film and a reflective film in this order proceeding from the pixel electrode, wherein, said common electrode, said pixel electrode, said reflective film and said interlayer insulating film have substantially identical projecting patterns in registry with each other on front surface sides facing said second substrate, said pixel electrode conforms to the shape of a surface of the interlayer insulating film facing the second substrate; said slits and said projecting patterns extend along parallel lines, said slits are positioned between lines of said projection patterns, flat surfaces exist on said interlayer insulating film between said lines of projection patterns, said common electrode has flat portions between its lines of projection portions, and the pixel electrode and the common electrode are arranged so that electric field intensities between the pixel electrode and the common electrode are uniform in the reflective display area.
