Abstract
A liquid crystal display device according to an exemplary aspect of the invention includes a thin film transistor (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, the pixel electrode and the first surface common electrode are arranged so that an electric field along a principal plane of said TFT substrate can be applied to the liquid crystal, a second surface common electrode is formed on the counter substrate, a same common electric potential is inputted into the second surface common electrode as well as into the first surface common electrode, the second surface common electrode is opposed to the first surface common electrode, and the second surface common electrode is arranged so that an electric field along a principal plane of the counter substrate can be applied to the liquid crystal.
