Abstract
A gradation voltage corresponding to a display data is input to a signal electrode driving circuit. The signal electrode driving circuit includes a voltage output circuit which outputs a drive voltage corresponding to the input gradation voltage, and a slew rate assist circuit which accelerates a transition of an output voltage of the voltage output circuit. The slew rate assist circuit accelerates the transition of the output voltage after a predetermined time from a start of transition of the gradation voltage.
