The present invention relates to a plasma display panel, and more particularly, to a method for driving a plasma display panel. The driving method of the plasma display panel according to the present invention comprises the steps of: supplying alternately a sustain pulse to a scanning electrode and a sustain electrode during a sustain period; and supplying a DC voltage of positive polarity to an address electrode during a part of the sustain period. According to the driving method of the plasma display panel of the present invention, it is possible to achieve a stable address discharge and to prevent the damage of the circuit components and the erroneous discharge owing to excessive voltage fluctuation.
