Provided is a method for driving plasma display panel capable of changing the quantity of emission in an erasure discharge. The method drives a plasma display panel including a scan electrode drive circuit (3) for driving scan electrodes (112), a sustain electrode drive circuit (2) for driving sustain electrodes (111), an address electrode drive circuit (4) for driving address electrodes (121), and a control circuit (5) for controlling the actions of the individual drive circuits. The individual drive circuits are driven for a reset period, in which one field is divided for actions into a plurality of sub-fields for adjusting the electric charges in cells, for an address period, in which cells to be issued are designated, for a sustain period, in which discharges are repeated with the scan electrodes and the sustain electrodes to cause the emissions of the cells, and for an erase period, in which the quantity of wall charges formed in the cell having emitted finally of the sustain period is reduced. Erasure waveforms of at least two kinds having different emission quantities are selected and applied by the drive method of the erase period. The erasure waveforms are arbitrarily selected for the erase period of each sub-field.
