ABSTRACT:
It is intended to increase the display speed in an active matrix liquid crystal display device. In displaying a moving picture, different voltages are applied in two steps to each pixel, i.e., each liquid crystal cell. More specifically, after a high voltage is applied first, and then a low voltage is applied at a prescribed timing, so that the rising characteristic of the liquid crystal is improved. In a specific configuration, thin-film transistors are provided on both sides of a pair of electrodes between which the liquid crystal is interposed. A voltage for accelerating the liquid crystal operation is applied from one of the two thin-film transistors, and the same voltage as in the case of displaying a still picture is applied from the other thin-film transistor.
