Method for producing image on liquid crystal panel, liquid crystal panel and liquid crystal display equipped with the same

摘要

A liquid crystal panel has a cholesteric filter and the quarter wave plate inserted between a glass substrate and color filter elements, and each section of the cholesteric filter reflects either right-handed or left-handed circularly polarized light component recognized as one of the three primary colors and the circularly polarized light components recognized as other primary colors toward a light source so as to recycle these circularly polarized light components, thereby enhancing the utilization factor of incident light without increase of power consumption.
