Abstract
Power consumption in an active matrix type liquid crystal display device having partial display function is reduced. In one frame period, a display area corresponding to first 80 horizontal periods, that is the first line through the 80th line, is set as a partial display area and a display area corresponding to the remaining 239 lines is set as a background display area. And a partial display area control signal ENBSC is set at a low level and an SC inversion drive is performed in the partial display area. The partial display area control signal ENBSC is fixed at a high level in the background display area and all of SC inversion control units corresponding to the background display area halt their operation.
