Patent ID: 8314915

Claim:
A liquid crystal display panel, comprising: a pair of substrates which are disposed so as to be opposite each other and have a liquid crystal layer interposed therebetween, wherein a first one of the pair of substrates includes: a plurality of scanning lines and signal lines which are arrayed on a display region so as to form a matrix shape; a common wiring formed on a peripheral area surrounding the display region; an interlayer film formed so as to cover at least the whole of the display region; pixel electrodes composed of a transparent conductive material, which are formed on the surface of the interlayer film in accordance with respective pixel areas partitioned by the plurality of scanning lines and the signal lines; an inter-electrode insulating film formed on the pixel electrodes and the interlayer film within the display region; and a common electrode composed of a transparent conductive material, which is formed on the whole of the inter-electrode insulating film, includes sections each having a plurality of slits formed therein, corresponding to respective pixel areas, and is electrically connected to the common wiring, wherein a second one of the pair of substrates includes: a base; a color filter layer formed on the base; and a black matrix formed between the base and the color filter layer. wherein, a conductive layer is formed directly on the top surface of the common electrode, the conductive layer being composed of a material of a conductivity superior to a conductivity of the transparent conductive material composing the common electrode, is formed, in plan view, at locations overlapped with locations at which the plurality of scanning lines and the signal lines are formed, wherein the common electrode is electrically connected to the common wiring through a plurality of first contact holes, and the conductive layer is directly electrically connected to the common wiring through a plurality of second contact holes, and wherein the interlayer film is formed to cover the signal lines.
