Abstract
A reflection type liquid crystal display comprises a substrate (10) provided with a TFT and a reflective display electrode (50) connected to the TFT, a counter electrode substrate (30) having a color filter (31), and a counter electrode (34), and provided with a light diffusing layer (43), a phase plate (44) and a polarizer (45) on the side of an observer 101, and a liquid crystal (21) held between the substrates. The surface of the reflective display electrode (50) facing the liquid crystal (21) is concaved toward the substrate (10), so that a reflected light is prevented from leaking to adjacent pixels, and prevented from being radiated to a black matrix in the vicinity of the pixels. A bright display can be obtained a wide viewing angle.
