The invention concerns a display screen with active matrix comprising first and second transparent substrates enclosing a crystal liquid material, at least one counter electrode, pixel electrodes in lines and in columns, data lines, perpendicular selection lines, control devices for connecting the lines to the pixel electrodes, the pixel electrodes being controlled such that the electrodes connected to a common selection line have the same polarity while, for two adjacent selection lines the polarity is reversed, the pixel electrodes being located in a first plane while the other elements are located in a second plane distanced from the first plane, and a transparent mass plane being located between the two planes. Moreover, the mass plane has a structure such that at least the part found between two pixel electrodes of same polarity is recessed. The invention is applicable to LCD.

A biased bending vertical alignment mode liquid crystal display is provided. The liquid crystal display includes a first substrate having a first electrode, a second substrate having a second electrode and a third electrodes, a plurality of first slits formed on the second electrode over the third electrodes, a plurality of second slits formed on the second electrode without covering the third electrodes, wherein the plurality of first slits and the plurality of second slits divide the second electrode into a plurality of fragmented electrode portions, and the plurality of first slits are alternate with the plurality of second slits, and a liquid crystal layer having a plurality of liquid crystal molecules and interposed between the first substrate and the second substrate.

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.
