Abstract

Abstract PURPOSE:To cut down cost and to reduce wiring resistance and to increase a rate of performation by forming a data line and a drain of a transparent conductor and metallic layers laminated on it and by forming an picture element electrode and a source of a transparent conductor. CONSTITUTION:The data line and the drain of a thin film transistor TFT are formed of the transparent conductor 13 and the metallic layer 16 and 17 laminated on it, and the picture element electrode and the source of the TFT are formed of the transparent conductor 13. The wiring resistance of a data line is reduced without reducing the numerical aperture. I.e., the resistance of the data line and the drain concerning with the propagation of a signal are low because the metallic layers 16 and 17 are laminated on th transparent conductor 13. Besides, since the picture element which acts to display and the source electrode are formed on only the transparent conductor, the rate of perforation of the source part can be increased as a display electrode. Thus, the efficiency of display can be improved and the cost can be cut down.
