PURPOSE:To reduce a coloring phenomenon of display at the inactive time, and to execute the display having no interference color, by providing an electric power supply means on only one liquid crystal layer of a double-layer type twisted mnematic liquid crystal display device, and making the other liquid crystal layer function as a correction plate. CONSTITUTION:The double-layer type structure of this display device is obtained by combining a display cell consisting of transparent electrodes 2a, 2b, liquid crystal molecule oriented layers 3a, 3b, and a twisted mnematic liquid crystal layer 4a, and a display cell consisting of liquid crystal molecule oriented layers 3c, 3d and a twisted mnematic liquid crystal layer 4b, so that an effect of a liquid crystal display device which has combined an optical correcting plate (compensator) can be obtained, and in this way, a coloring phenomenon due to an interference color of an inactivated part is reduced remarkably as to a liquid crystal cell which is suitable for multiplex driving and has a small value of d.DELTAn. |
