Abstract
To be realized the well-lighted display by using the whole pixels in the reflective mode and the transmissive mode. In a reflective mode, an optical elementis used as liquid crystal display element. That is, the optical elementoperates as liquid crystal display element by applying the voltage. In this case, the optical elementreflects the external light since the optical elementis a scattering state with regard to non-applying pixel (arrow B). In a transmissive mode, a liquid crystal panelis used as liquid crystal display element. That is, the liquid crystal paneloperates as liquid crystal display element by applying the voltage. In this case, the optical elementpasses light from a backlightsince the optical elementis a transmissive state (arrow A). And the optical elementplays a color filter part and does not operates as display element.
