Title: Liquid crystal panel and liquid crystal projector using the same
Inventor: OMAE HIDEKI
IPC: G09G3/36
Filed: 1992-11-18
Abstract: PURPOSE:To provide a liquid crystal panel and a liquid crystal projector with high luminance and high contrast. CONSTITUTION:A diffraction grating 19 is formed on at least one of the picture element electrode 13 and the counter electrode 14 of the liquid crystal panel, and the picture element electrode 13 is set as a reflection electrode. The diffraction grating 19 is formed by using a material having refractive index the same as or in the neighborhood of the apparent refractive index of a liquid crystal layer 15 when no electric field is applied to the liquid crystal panel. Since no difference of refractive index the diffraction grating 19 and the liquid crystal layer 15 exists when the liquid crystal is set in an off-state, light can advance linearly. When the liquid crystal is set in an on-state, the refractive index of the diffraction grating 19 differs from that of the liquid crystal layer 15, therefore, incident light on the liquid crystal panel is diffracted.
