Abstract:
A liquid crystal display device comprising:two opposing substrates, at least one which is transparent, a liquid crystal layer interposed therebetween; pixels formed over at least one of the two substrates, said pixels having a pixel electrode; a thin film transistor connected to said pixel electrode of said pixels, said thin film transistor having a semiconductor layer with a first surface and a second surface; a first gate electrode of said thin film transistor of said pixels located at a side of the first surface of said semiconductor layer; a second gate electrode of said thin film transistor of said pixels located at a side of the second surface of said semiconductor layer; a plurality of first scanning signal lines connected to said first gate electrode of said thin film transistor of said pixels for applying a control voltage to said first gate electrode of said thin film transistor of said pixels, said first scanning signal lines being located at the side of the first surface of said semiconductor layer; a plurality of second scanning signal lines connected to said second gate electrode of said thin film transistor of said pixels for applying a control voltage to said second gate electrode of said thin film transistor of said pixels, said second scanning signal lines being located at the side of the second surface of said semiconductor layer; and a conductor layer which is extended from a source area of said thin film transistor and interposed between said first scanning signal lines and said second scanning signal lines; wherein said thin film transistor is controlled by at least one control voltage applied to said first gate electrode and said second gate electrode.
