ABSTRACT:
The invention relates to an active matrix liquid crystal display device based on voltage control (non-zero driving voltage) of the birefringence (negative or positive) of the liquid crystal cell. In the device a ground (earth) plate comprises a piece of glass with a transparent conductive coating, such as indium tin oxide. A silicon wafer with integrated circuits on it has a coating of polymer for aligning liquid crystal molecules. The coated glass also has a coating for aligning the liquid crystal molecules.
