Abstract
The invention prevents disconnection of data lines that traverse two-layered gate lines via an insulating film. Data linesoverride and thereby traverse gate lineswith an insulating film deposited therebetween. The gate lineseach have a two-layered structure including a lower AlCu layerand an upper MoCr layer. When the thickness ratio of the upper layerto the lower layeris in the range of 0.4 to 1.0, it is possible to prevent a decrease in the etch speed of the upper layernear the side edges of the gate line, which occurs due to galvanization. As a result, the upper layeris prevented from having an overhang. The absence of overhangs on the gate linesprevents the data linesfrom being disconnected at the intersections of the gate linesand the data lines
