Abstract

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.
