PROBLEM TO BE SOLVED: To realize a new method for driving a plasma display panel of high brightness and low power consumption by more increasing an effect of improvement in a light emission efficiency of a discharge sustaining pulse. SOLUTION: This relates to a method for driving a plasma display panel 10 which is provided with a plurality of 1st and 2nd electrodes 1, 2 and a plurality of 3rd electrodes arranged orthogonal thereto, and in which display cells 10A are formed at the crossing parts of the electrodes, and in the driving method of the plasma display panel provided with a reset period, an address period, and a discharge, sustaining period, wall charges of the opposite polarity are made to remain on the electrodes of turned-off cells at the end of the address period; the discharge sustaining pulses include 1st and 2nd discharge sustaining pulses opposite in the polarity; the absolute value of the maximum voltage of the 1st discharge sustaining pulse is large than that of the 2nd discharge sustaining pulse; the polarity of the 1st discharge sustaining pulse is opposite to that of the remaining wall charges of the turned-off cells; and the voltage of superposing the voltage generated by the remaining wall charge of the turned-off cells on the 1st and 2nd discharge sustaining pulses is lower than the starting voltage.
