Abstract
To provide a liquid crystal display device easily produced having no disclination which causes a light leak, an excellent visual angle and an excellent contrast ratio, a liquid crystal layer is interposed between two substrates, two or more of micro areas coexist with each other in the liquid crystal layer, and liquid crystal molecules in the micro areas build up from a center of each pixel. A potential of a second electrode disposed on an opening is made approximately identical with that of a counter electrode, and a potential of a peripheral electrode is higher than that of the counter electrode, thereby obtaining the liquid crystal display device in which the liquid crystal molecules build up from the center of each pixel. Thus, the liquid crystal display device easily produced having a wide visual angle and an excellent contrast ratio is obtained. In addition, a polymer organic compound is dispersed in the liquid crystal to fix a built up direction of the liquid crystal molecules.
