A stable address operation is performed also when a plasma display panel having a high definition and large screen is driven. For this purpose, a driving method of a plasma display panel is provided. The panel is driven by forming one field using a plurality of subfields each of which has an address period and a sustain period in which sustain pulses varying from a base potential to a voltage at which a sustain discharge is caused in the discharge cell having undergone the address discharge are applied to the display electrode pairs. In the driving method, after generation of the final sustain pulse in the sustain period, an up-ramp waveform voltage which increases from the base potential to a predetermined voltage is applied to the scan electrodes. The predetermined voltage is set lower than the voltage of the sustain pulses.
