ABSTRACT:
An active matrix liquid crystal display device operates such that the polarity of a voltage on a common electrode30is inverted by row or by frame. A charge collection/resupply circuit includes a switch connected between the common electrode and a common voltage output buffer, a charge collection capacitor, and a switch connected between a connection point of the common electrode and the switch and the charge collection capacitor. The switch control unit is configured to operate such that immediately before a polarity of a common voltage VCOM10is inverted, the switch11is turned off and then the switch12is turned on, and further, after inversion of the polarity of the common voltage VCOM, the switch is turned off and then the switch is turned on.
