Abstract
A liquid crystal layer is composed of a liquid crystal composition having a positive dielectric anisotropy, and the liquid crystal composition is sandwiched by a pair of transparent substrates while being twisted by 220 to 260 degrees. Also, in a liquid crystal display device having an optical compensating plate and a polarizer respectively formed above and below a liquid crystal cell, a transflector is formed on the inner surface of the transparent substrate of the liquid crystal cell, the transflector has a high-reflectivity film having a plurality of fine apertures therein, and the high-reflectivity film has a diffuse reflection surface, on the surface thereof, having a controlled reflected luminance characteristic.
