<p>A liquid crystal modulation element and a projection-type liquid crystal display apparatus are provided for maintaining colour purity and improving luminance of an image. Microlenses (822) each provided for every three pixel electrodes (812B, 812R, 812G) condense colour rays of B, R and G incident at mutually different angles and have the rays enter the pixels of the respective colours. Trimming filters (814B, 814R, 814G) are each provided on the respective pixel electrodes (812B, 812R, 812G) for intercepting rays leaking onto the own pixel electrode of the colour rays to enter the neighbouring pixel electrodes. As a result, a reduction in colour purity due to colour mixture is prevented even if the incident divergence angles of the colour rays entering a liquid crystal panel are large. Since the incident divergence angles may be relatively large, the amount of diaphragming in the optical projection system may be reduced. A large quantity of light is thereby obtained. <IMAGE></p> |
