摘要
An active matrix type liquid crystal display device carries out half-tone display with an area gray scale display method, according to which a pixel is composed of a plurality of subpixels and the area of display regions is changed by an image signal that is a binary signal. The amplitude of an opposite electrode is optimized by configuring a data signal line driving circuit with a scanning circuit, latch-in circuits and outputting circuits. This eliminates the needs to externally input an analogue signal and an intermediate voltage, and enables the driving circuit to be configured only with digital circuits. The driving circuit is integrated to prevent increases in cost of the driving circuit and of mounting the driving circuit that are caused by an increase in the number of data signal lines as a result of the adoption of the area gray scale display method. Consequently, it becomes possible to make an attempt to reduce the cost, power consumption and non-defective ratio of the entire system.
