Patent ID: 7605898

Claim:
A liquid crystal display device comprising: a first substrate which forms pixel electrodes, counter electrodes, thin film transistors and pixel regions thereof; a second substrate which faces the first substrate in an opposed manner; and a liquid crystal layer provided between the first substrate and the second substrate, wherein each of the pixel regions is surrounded by a pair of gate lines and a pair of drain lines, each of the pixel electrodes is formed in a corresponding one of the pixel regions respectively, each of the pixel electrodes is formed in a rectangular shape which substantially covers said corresponding pixel region in a plan view, each of the counter electrodes is formed in a comb shape in the plan view and has teeth portions, at least a portion of said each pixel electrode overlaps a corresponding one of the thin film transistors in the plan view via a first insulation film provided therebetween, said each pixel electrode is connected to an output electrode of the thin film transistor via a contact hole which is formed in the first insulation film, the contact hole being disposed in said corresponding pixel region and covered with said each pixel electrode, said each counter electrode is arranged at a position above an entire portion of said each pixel electrode with a second insulation film in-between in an area where the teeth portions of said each counter electrode overlap said each pixel electrode in the plan view, said each counter electrode is formed at a position avoiding the contact hole formed in the first insulation film in the plan view, and at least one of the teeth portions of said each counter electrode overlaps the thin film transistor in the plan view.
