Abstract:
A liquid crystal display device comprising:a first polarizer plate, a first substrate, a liquid crystal layer, a second substrate and a second polarizer plate disposed in this order;an active matrix drive electrode group including a plurality of pairs of electrodes, each pair of which is assigned to one pixel, formed on a surface, which is adjacent to said liquid crystal layer, of one of said first substrate and said second substrate; andan optical compensation film disposed between said first polarizer plate and said first substrate;wherein one of said first polarizer plate and said second polarizer plate has a transmission axis which is parallel to a liquid crystal retardation axis of said liquid crystal layer in a state displaying a black, and the other has a transmission axis which is perpendicular to said liquid crystal retardation axis; andwherein a smaller angle of angles formed by a film retardation axis of said optical compensation film and said transmission axis of one of said first polarizer plate and said second polarizer plate is 0.degree..about.2.degree. or 88.degree..about.90.degree. wherein an in-plane retardation of said optical compensation film is 190 nm.about.390 nm and a retardation in a direction of thickness of said optical compensation film is 0.3.about.0.65.
