摘要:
A liquid crystal display device has good contact characteristics between an etched side end portion of a lower layer wiring line and an insulating film and the like, satisfactory step coverage, and satisfactory adhesion to a substrate so that disconnection of an upper layer wiring line and short-circuiting of the lower layer wiring line can be prevented to improve reliability. The liquid crystal display device comprises a wiring line having a laminated structure including a first layer which is made from a first metal layer formed over an insulating substrate and a second layer which is made from a second metal layer different from the first metal layer and is formed over the first metal layer, and the side end face of the first layer has a right-tapered shape with a taper angle of 60° or less, while the side end face of the second layer is approximately perpendicular to or counter-tapered with respect to the insulating substrate. The second layer has a thickness not greater than ½ of that of the first layer.

A liquid crystal display unit is used that has data lines made of a molybdenum-alloyed film having a chromium content from 2 wt. % or more, but up to 5 wt. %, or a molybdenum-alloyed film lamination (Mo—Cr) consisting of a first electroconductive film and a second electroconductive film, with the first electroconductive film having a chromium content from 2 wt. % or more, but up to 5 wt. % and the second electroconductive film being provided above the first electroconductive film and containing less chromium than the first electroconductive film does. The use of the data lines composed of these materials enables the following requirements to be satisfied: high dry-etching resistance, low resistance, low ACF contact resistance, low side etching rates, forward tapered wiring cross-sectional shape, and up to two lamination layers.
