Abstract
In a liquid crystal display device, an X-driver circuit and a Y-driver circuit are associated with each other to thin out image to be displayed in a display area, under the control of a control circuit. A common electrode drive circuit supplies a common electrode signal to a common electrode under the control of the control circuit. In a canceled scanning period, average-correction is performed to average a polarity inversion time of the common electrode signal for driving the common electrode.
