Characteristics of an active-matrix LCD (Liquid Crystal Display) module utilizing two-terminal nonlinear element have been analyzed. The two-terminal nonlinear element, consisting of Metal/SiNxATO (Indium Tin Oxide) shows symmetric and steep diode characteristics. This nonlinear element is applied to 640 x 400 dots LCD which realizes contrast ratio of more than 20 in a reflective mode. Since the two-terminal element, composed of three thin film layers, has a simple structure, it can be produced with only two photolithographic fabrication processes. The LCD with those elements has the advantage of a large area display device capability. In this paper, the relations between the electro-optical characteristics of the LCD panel and the I-V (current voltage) characteristics of SiNx diode are discussed. The I-V diode characteristics can be adjusted to drive the liquid crystal by controlling the Si and N atomic ratio of the SiNx layer. Several parameters of the liquid crystal cell required for the diode matrix LCD are also discussed.
