PROBLEM TO BE SOLVED: To provide a method of neutralizing wall charges accumulated on electrodes in sub-fields where a strong discharge occurs, in a reset period in a driving method for a plasma display panel in which gray-scale levels are represented by a combination of sub-fields. SOLUTION: During a reset period of a first sub-field, a rising ramp pulse and a falling ramp pulse are applied to a first electrode to initialize wall charges of a discharge cell, and a self-erase discharge is generated in the case that a strong discharge occurs between the first electrode and a second electrode. During a reset period of a second sub-field, a falling ramp pulse is applied to the first electrode. During an address period, address data is applied to an address electrode to select the discharge cell when scan pulses from a scan high voltage to a scan low voltage are successively applied to the first electrode. During a sustain discharge period, a pulse having a sustain voltage is alternately applied to the first and second electrodes, and a sustain discharge occurs in the selected discharge cell.
