In a two-phase driving operation that is performed in at least a sub-field having a largest luminance weight, a first ramp waveform that drops from a first potential to a second potential is applied to a plurality of first scan electrodes, a second ramp waveform that drops from a third potential that is higher than the first potential to a fourth potential that is higher than the second potential is applied to a plurality of second scan electrodes in a setup period, and a scan pulse is sequentially applied to the plurality of first scan electrodes, and then a scan pulse is sequentially applied to the plurality of second scan electrodes in a write period. The two-phase driving operation is employed to prevent a discharge failure during a write discharge.
