Patent ID: 8773341

Claim:
A liquid crystal display device comprising: a liquid crystal panel including liquid crystal sealed between a pair of substrates; a plurality of gate signal lines and a plurality of drain signal lines formed to cross each other on one of said pair of substrates; a pixel region surrounded by a pair of adjacent gate signal lines and a pair of adjacent drain signal lines; a thin film transistor provided in the pixel region and connected to at least one of the pair of adjacent gate signal lines and at least one of the pair of drain signal lines; a pixel electrode provided in the pixel region and configured to be supplied with a video signal via the thin film transistor; and a counter electrode provided in the pixel region and configured to be supplied with a reference signal via a counter voltage signal line, the reference signal being a reference for the video signal, wherein: said counter electrode is comprised of a transparent conductive film, said pixel electrode is comprised of a transparent conductive film, on a liquid crystal side relative to said counter electrode, an insulating film is provided between said counter electrode and said pixel electrode, said counter voltage signal line is formed to extend in a longitudinal direction which is the same direction in which said plurality of gate signal lines longitudinally extend so as to overlap with at least one of said plurality of gate signal lines, said insulating film is provided between said counter voltage signal line and the at least one of said plurality of gate signal lines, and said counter voltage signal line is at least partially formed between said counter electrode and said liquid crystal and is electrically connected to said counter electrode via a contact hole formed in said insulating film, said pixel electrode and said counter voltage signal line are formed on said insulating layer which is formed between the pixel electrode and the counter electrode so that the pixel electrode is located closer to the liquid crystal than the counter electrode, and wherein said pixel electrode and said counter voltage signal line are formed in the same layer.
