Patent ID: 8189157

Claim:
A liquid crystal display device comprising: a pair of transparent substrates which clamp a liquid crystal layer therebetween, one of the transparent substrates carrying a plurality of scanning lines and signal lines arranged in matrix with a first insulation film therebetween on a surface adjacent to the liquid crystal layer thereof, switching devices made of a thin film transistor, the switching devices being positioned at vicinities of intersections of the scanning lines and the signal lines, an intermediate film overlying a entire surface of a displaying area, first electrodes made of a transparent conductive material and connected to electrodes of the switching devices via contact hole portions formed through the intermediate film each contact hole portion positioned in each of regions defined by the scanning lines and the signal lines, second electrodes made of a transparent conductive material, and a second insulation film sandwiched between the first electrodes and the second electrodes, wherein the electrodes of the switching devices are directly covered with the intermediate film; wherein channel regions of the switching devices are directly covered with the second insulation film at opening portions formed in the intermediate film; wherein the second electrodes are, as a unit, connected to a common line wired on an external periphery of the displaying area; and wherein the second insulation film is made of an inorganic transparent insulation material.
