ABSTRACT:
A liquid crystal display device is provided with an electrode structure for effective utilization of optically isotropic liquid crystals. Such a liquid crystal display device comprises a first substrate; a second substrate; polarizing plates provided on the first substrate and the second substrate, respectively; a liquid crystal layer disposed between the first substrate and the second substrate; and pixel electrodes and common electrodes provided on the first substrate, wherein the liquid crystal layer has such a property that optical anisotropy is induced therein by a change of an optically isotropic state caused by a voltage; wherein ones of the pixel electrodes and the common electrodes are formed in an inter-digital form, while the other ones are formed in a flat plate, and wherein an electric field is applied to the liquid crystal layer by a potential difference between the pixel electrodes and the common electrodes.
