Abstract
One display frame period is divided into one or a plurality of display driving periods and non-display driving periods, and immediately before transition from the non-display driving period to the display driving period, a dummy driving period is inserted. During the dummy driving period, using dummy data changed from display data at the time of driving stop of a signal electrode during the non-display driving period, driving of the signal electrode starts. Thereafter, a display line is selected, and, using the display data corresponding to each display line selected, the signal electrode is driven.
