Abstract
A projection type liquid crystal display apparatus comprising a plurality of laminated liquid crystal panels, each of which has a twisted nematic type liquid crystal layers and voltage applying means for modulating light that has passed through the liquid crystal layer by one display element unit, wherein the twisting direction of the liquid crystal molecules of the liquid crystal layer of one of the adjacent liquid crystal panels is opposite to that of the liquid crystal layer of the other liquid crystal panel; the orientation of the liquid crystal molecules of the liquid crystal layer of the first one liquid crystal panel in the vicinity of the liquid crystal layer of the other liquid crystal panel is approximately perpendicular to that of the liquid crystal molecules of the liquid crystal layer of the other liquid crystal panel in the vicinity of the liquid crystal layer of the first one liquid crystal panel; and the respective voltage applying means of each of the liquid crystal panels are provided with picture element electrodes that are disposed in a zigzag manner so that the picture elements of the first one liquid crystal panel are not superposed on those of the other liquid crystal panel in the light transmitting direction, whereby the opening ratio of the display apparatus becomes high and the display capacity can be increased.
