PROBLEM TO BE SOLVED: To provide a method of driving a plasma display panel (PDP) that can increase dark contrast without causing erroneous discharge. SOLUTION: A reset process and a sustain process are performed in one of subfields in a unit display period. In the reset process, a reset pulse is applied to row electrodes of the PDP to initialize each discharge cell to an emission mode (or non-emission mode). In the sustain process, a sustain discharge is repeatedly generated the number of times corresponding to the number of times a sustain pulse is to be applied, in only discharge cells that are in the emission mode. In this case, a peak potential of the reset pulse is changed based on the number of those discharge cells that are maintained in the non-emission mode during the unit display period and the number of times the sustain pulse is to be applied in the sustain process in this subfield.
