Patent ID: 7064799

Claim:
A semi-transmissive-type liquid crystal display device comprising: a first substrate including a plurality of signal electrodes being arranged in parallel to one another along a first direction, a plurality of scanning electrodes being arranged in parallel to one another along a second direction orthogonal to said first direction and a plurality of pixel regions each having a pixel electrode being placed in a one-to-one correspondence to an intersection between each of said signal electrodes and each of said scanning electrodes; a second substrate; a liquid crystal layer inserted between said first substrate and said second substrate; a backlight source to feed light to said liquid crystal layer; and wherein each of said pixel regions includes a reflective region having a reflective film to receive ambient light from an outside and to display in a reflective manner while being in a reflective display mode, and a transmissive region having a transparent electrode film to allow light from said backlight source to be transmitted to display in a transmissive manner at time of operations in a transmissive display mode, said transparent electrode film in the transmissive display mode serving as said pixel electrode and said reflective film in the reflective display mode serving as said pixel electrode; and wherein in each of said pixel regions, said transparent electrode film is extended to said reflective film in a manner to cover at least one part of said reflective film, said first gap and said second gap being approximately equal when said twisted angle is about 72°.
