Abstract:
A liquid crystal display device comprising a pair of substrates, and a liquid crystal layer supported between said pair of substrates, said liquid crystal display device further comprising:a plurality of gate electric wirings provided on one of said pair of substrates;a plurality of drain electric wirings respectively intersecting with said plurality of gate electric wirings in a matrix configuration;a plurality of thin film transistors formed on respective points of said gate electric wirings and said drain electric wirings;a plurality of common electric wirings extending in the same direction as said gate electric wirings;a plurality of picture elements, at least one of said picture elements being respectively surrounded by said gate electric wirings and said drain electric wirings; anda plurality of counter electrodes connected to said common electric wirings and extending in the same direction as said drain electric wirings, a plurality of picture element electrodes made of at least one of conductive oxide and graphite being connected to said thin film transistors and extending in the same direction as said drain electric wirings;wherein an electric field having a component parallel to one of said pair of substrates is produced in said liquid crystal layer by an electric voltage applied between said counter electrodes and said picture element electrodes, and said respective picture element electrodes are separated from said liquid crystal layer by at least an alignment film which aligns molecules of said liquid crystal layer in a predetermined direction.
