ABSTRACT:
A liquid crystal display device of the present invention includes a TFT substrate having a substrate and a display pixel arranged in a matrix form on the substrate, a counter substrate opposed to the TFT substrate and being stuck therewith and a liquid crystal enclosed between the TFT substrate and the counter substrate, the pixel electrode and the first common electrode are arranged so that an electric field along a principal plane of the TFT substrate can be applied to the liquid crystal, a second common electrode for inputting a common electric potential is formed on the counter substrate, the second common electrode is opposed to the first common electrode, and a conduction part for electrically connecting the second common electrode and the first common electrode mutually and transmitting the common electric potential to the first common electrode is formed near each display pixel or near a predetermined display pixel.
