Patent ID: 7961286

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 regions in a plan view, each of the counter electrode is formed in a comb shape in a plan view and has teeth portions, a display region which contributes to a display is formed in said each pixel region, at least a portion of said each pixel electrode overlaps a corresponding one of the thin film transistors in a 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 the display region formed in said corresponding pixel region and covered with said each pixel electrode, said each counter electrode is arranged at a portion 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, and at least one of the teeth portions of said each counter electrode overlaps a semiconductor layer of the thin film transistor in the plan view.
