Liquid crystal display device with field sequential light source and optical medium

Abstract

A liquid crystal display device exhibits high reliability and is capable of miniaturization by eliminating a mechanical operating mechanism. At least a light guide plate which guides light from a light source, a liquid crystal display panel, an optical medium which changes over transmission and reflection of light, color filters and a reflector are sequentially arranged from the viewer side. The color of the light from the light source are sequentially changed over to provide three primary colors, and this light passes through the liquid crystal display panel and is reflected toward the viewer side by the optical medium. The color filters are constituted for respective primary colors and are arranged to face at least three pixels which are disposed close to each other. The reflector reflects ambient light which passes through the light guide plate, liquid crystal display panel, optical medium and color filters to the viewer side.
