Patent abstract
A reflective liquid crystal display includes a linear polarizer for converting natural light into linearly polarized light; a retardation film for converting the linearly polarized light into circularly polarized light; a liquid crystal layer for varying the phase of the light differently depending on the presence or absence of an electric field; a cholesteric liquid crystal color filter for selectively reflecting light received from the liquid crystal layer; and a black background for absorbing light passing through the color filter.
