A driving method of a plasma display panel. A second voltage is applied to a first electrode being selected in an order in which a plurality of first electrodes are selected, the second voltage being higher than a first voltage being applied to other first electrodes in a subfield of a first group of subfields. A fourth voltage is applied to the second electrode of a discharge cell being turned on among a plurality of discharge cells located in the first electrodes, the fourth voltage being lower than a third voltage being applied to other second electrodes. The discharge cell being turned on is selected in the subfield of the first group of subfields. Sustain discharge is performed at the selected discharge cell.
