A reflection type liquid crystal display comprises a substrate ( ) provided with a TFT and a reflective display electrode ( ) connected to the TFT, a counter electrode substrate ( ) having a color filter ( ), and a counter electrode ( ), and provided with a light diffusing layer ( ), a phase plate ( ) and a polarizer ( ) on the side of an observer , and a liquid crystal ( ) held between the substrates. The surface of the reflective display electrode ( ) facing the liquid crystal ( ) is concaved toward the substrate ( ), 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.
