A reflective liquid crystal display device employing only one sheet of polarizer film. An optical compensator of a hybrid tilt type having retardation rc is disposed between a liquid crystal cell and the polarizer film disposed only on one side of the liquid crystal cell. When an effective voltage von is applied to the liquid crystal cell, the retardation rc of the optical compensator is determined to accomplish the following relation: ron+rc=λ/4+m·λ/2(m=0, 1, 2 . . . ) Or ron+rc=(m+1)·λ/2(m=0, 1, 2 . . . ) where ron is retardation of the liquid crystal layer and λ is the optical wavelength. This disclosure enables the a reflective liquid crystal display device with brighter white display, higher contrast, achromatic monochrome display, and broader viewing angle to be constructed.
