Abstract:
1. A liquid crystal display device comprising: a liquid crystal layer clamped between a first transparent substrate and a second transparent substrate; a plurality of gate lines provided on the first transparent substrate; a plurality of drain lines disposed to intersect the plurality of gate lines in matrix form on the first transparent substrate; pixels respectively formed by areas each surrounded by adjacent ones of the plurality of gate lines and adjacent ones of the plurality of drain lines, each of the pixels having at least one TFT element and a pixel electrode to which a signal from one of the adjacent drain lines is selected in accordance with a signal from one of the gate lines by the TFT element and is electrically supplied; a semiconductor layer forming the TFT element; and a capacitance line forming a capacitance element with an insulating layer interposed between the semiconductor layer and the capacitance line, a potential difference of polarity capable of bringing the semiconductor layer into a conductive state being approximately constantly applied between the semiconductor layer and the capacitance line.
