摘要： 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.

摘要： A liquid crystal display device has gate signal lines extending in the x-direction and arranged in the y-direction, and drain signal lines extending in the y-direction and arranged in the x-direction on the surface of the liquid crystal side of the one transparent substrate between a pair of transparent substrates opposed to each other via liquid crystals. A thin-film transistor is fumed on by a scanning signal from a gate signal line, and a pixel electrode will be supplied with a video signal from the drain signal line via the thin-film transistor that is fumed on in each of the regions surrounded by the signal lines. The thin-film transistor is of the MIS type, and the capacity between the gate electrode and the source electrode thereof is small on the input terminal side of the gate signal line and increases in a direction toward the end of the gate signal line, thereby to suppress the occurrence of flickering.

摘要： A liquid crystal display device includes pixels, each of which includes a first transistor and a second transistor. The size of the first transistor is larger than the size of the second transistor. In addition, channel widths and gate widths for the first transistor are larger than those of the second transistor. Also, the first transistor is located to be closer to a drain signal line provided for the pixel than the second transistor. In normal operation, the first transistor is coupled to the drain signal line and the second transistor is floating. However, if an abnormality occurs in the first transistor, it is cut off from the drain signal line and the second transistor is connected to the drain signal line by a repair line.
