Abstract
Between a substrate comprising reflective display electrodes each including a flat portion, a slope portion, and a base portion, and TFTs, and an opposing substrate on which a color filter and an opposing electrode is accumulated, and on the side of viewer, a light diffuser layer having the haze value of 33%, a retardation film, and a polarization film are provided, liquid crystal is disposed. The angle of inclination (angle of elevation) of the slope portion (SL) with regard to the base portion is greater than 0° and 8° or less. With this structure, it is possible to provide a reflective LCD capable of achieving increased luminance in each display pixel and of providing bright display over a wide range of viewing angles.
