Abstract
A reflection type liquid crystal display apparatus can avoid degradation of a reflection surface or an electrode terminal, provide a multiple color display with high color purity, and reduce fluctuation of voltage due to loss of a drive voltage or capacitive coupling, even when a color filter is provided on a substrate on the side of a reflection plate, thereby to realize a bright display having a high contrast. The reflection type liquid crystal display apparatus has a pair of substrates, a pair of orientation films disposed between the pair of substrates, a liquid crystal layer disposed between the pair of orientation films, a plurality of electrodes disposed respectively opposing the substrates and the orientation films, a reflection layer disposed between a plurality of the electrodes and the substrates within a space defined between one of the substrates and one of the orientation films, and at least one or more thin films having an insulating property arranged between the plurality of electrodes and the reflection layer.
