Abstract
A color liquid crystal display device which separates white light in to component colors. The separated colors are modulated by a reflective liquid crystal display. A lens group between the light separator and the reflective liquid crystal display condenses the entering light to each pixel of the liquid crystal display. High brightness and aperture efficiency are achieved by including in the lens group a birefringent material so that a different optical function is performed relative to the entering light fluxes and the modulated light fluxes.
