Abstract

A reflective liquid crystal (R-LCD) display device in which both the residual retardance of an R-LCD and the skew-angle effect of the analyzer may be compensated by a single compensator which has its optical axis oriented at an angle of from 1 to 30 degrees to the plane of polarization of the incident beam, eliminating the need for two separate compensators.
