    摘要： A liquid crystal display device includes a pair of substrates, a liquid crystal layer supported between the pair of substrates, a plurality of gate electric wirings provided on one of the pair of substrates, a plurality of drain electric wirings respectively intersecting with the plurality of gate electric wirings in a matrix configuration, a plurality of thin film transistors formed on respective points of the gate electric wirings and the drain electric wirings, a plurality of common electric wirings extending in the same direction as the gate electric wirings, a plurality of picture elements with at least one of the picture elements being respectively surrounded by the gate electric wirings and the drain electric wirings, and a plurality of counter electrodes connected to the common electric wirings and extending in the same direction as the drain electric wirings. A plurality of picture element electrodes made of at least one of conductive oxide and graphite are connected to the thin film transistors and extend in the same direction as the drain electric wirings. An electric field having a component parallel to one of the pair of substrates is produced in the liquid crystal layer by an electric voltage applied between the counter electrodes and the picture element electrodes, and the respective picture element electrodes are in contact with the liquid crystal layer directly or through an alignment film.
