Patent ID: 7602452

Claim:
A liquid crystal display device, comprising: a transparent substrate; a plurality of signal lines and scan lines arranged on said transparent substrate in a matrix; a plurality of auxiliary capacitor lines provided between said scan lines so as to be in parallel with said scan lines; thin film transistors each provided in a vicinity of an intersection of said signal lines and scan lines; and pixel electrodes arranged in respective positions defined by said signal lines and said scan lines and each electrically connected to a drain electrode of said thin film transistor, said thin film transistor's gate electrode and said scan line being covered by a gate insulating film, and said thin film transistor's drain electrode extending to overlie said auxiliary capacitor line, with an insulating layer having a smaller thickness than that of said gate insulating film being interposed between the drain electrode and said auxiliary capacitor line, and therby forming an auxiliary capacitor, wherein the edges of said insulating layer, which is positioned above said auxiliary capacitor line, are positioned inside of the edges of said auxiliary capacitor line.
