Patent ID: 6891584

Claim:
A liquid-crystal display comprising: a dichroic circular polarizing layer which, of incident light transmits a circularly polarized light component of one direction, either right or left, and absorbs a circularly polarized light component of the other direction; a liquid crystal cell, including a liquid crystal layer that shifts the phase of light passing therethrough, and electrodes for applying an electric field to said liquid crystal layer, said liquid-crystal cell having the effect of shifting a circularly polarized light phase of incident light substantially by 0 to π, when said electrical field is applied to said liquid-crystal layer from said electrodes so as to change the retardation value thereof; and a polarization separation layer being made a circular polarization separation layer that, of the incident light thereto, transmits a light component of one circular polarization, either right or left, and reflects another circularly polarized light component having the opposite polarization.
