Abstract: A high quality liquid crystal display device has an alignment film with a photoconductive characteristic. Since a region having gate lines situated therebelow does not undergo irradiation of a backlight, no photoconductive effect can be obtained. A photoresist is disposed below the alignment film situated over the gate lines in order to transfer the charges in the region to an opening portion of the alignment film in an early stage. Since the photoresist has a thickness of about 1.5 ?m, which is 20 times or more the 70 nm thickness of the alignment film, the resistance in the lateral direction is low in a portion where the photoresist is present. Accordingly, since the charges on the alignment film present over the gate line transfer to the opening portion of the alignment film and are eliminated in an early stage, the residual image is eliminated in the early stage.

Abstract: The invention prevents disconnection of data lines that traverse two-layered gate lines via an insulating film. Data lines 20 override and thereby traverse gate lines 10 with an insulating film deposited therebetween. The gate lines 10 each have a two-layered structure including a lower AlCu layer 11 and an upper MoCr layer 12. When the thickness ratio of the upper layer 12 to the lower layer 11 is in the range of 0.4 to 1.0, it is possible to prevent a decrease in the etch speed of the upper layer 12 near the side edges of the gate line 10, which occurs due to galvanization. As a result, the upper layer 12 is prevented from having an overhang. The absence of overhangs on the gate lines 10 prevents the data lines 20 from being disconnected at the intersections of the gate lines 10 and the data lines 20.

A video signal line, a drain electrode, and a source electrode are simultaneously formed in the same layer. The video signal line includes three layers: a base layer, an AlSi layer, and a cap layer.

Thus, the formation of an alloy having a high etching rate on a part of the AlSi layer is prevented, precluding the occurrence of a break on the video signal line.
