ABSTRACT:
A liquid crystal display device has a liquid crystal display panel and a drive circuit for supplying gray scale voltages to pixels in the liquid crystal display panel. The drive circuit selects intended gray scale voltage levels from a gray scale voltage varying with time periodically by determining a timing corresponding to the intended voltage level of the gray scale voltage based upon a display data signal and time control signals supplied to the drive circuit. A stabilizer circuit is provided to a gray scale voltage line for supplying the gray scale voltage.
