Abstract:
A normally-white twisted-nematic mode LCD device includes a first optical compensation film between a light-incident-side polarization film and an LC cell, and a second optical compensation film between a light-emitting-side polarization film and the LC cell. The optical axis of the first (second) optical compensation film projected onto the substrate surface is substantially parallel to the longer axis of an equivalent refractive index ellipsoid of a residual retardation of the LC layer in the vicinity of a light-incident-side (light-emitting-side) substrate upon display of black color.
