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 desired gray scale voltage levels from a gray scale voltage varying with time in a staircase fashion, in accordance with display data, and supplies the selected gray scale voltage levels to the pixels. The drive circuit includes a stabilizer circuit provided to a gray scale voltage line for supplying the gray scale voltage varying with time.
