Abstract: In a driving method for a plasma display panel, in the initializing period in at least one of a plurality of subfields, selective initializing operation is performed that selectively causes initializing discharge only in a discharge cell having undergone address discharge in an immediately preceding address period. The selective initializing operation includes the step of applying first voltage to the sustain electrode and applying an up-ramp waveform voltage to the scan electrode, the step of applying a down-ramp waveform voltage to the scan electrode and then applying a positive rectangular voltage to it, and the step of applying second voltage higher than the first voltage to the sustain electrode and applying a down-ramp waveform voltage to the scan electrode.
