The wall charge is appropriately adjusted in the initializing period, and occurrence of an abnormal discharge and an unlit cell is suppressed in the address period. Therefore, a plasma display device has a plasma display panel having a plurality of discharge cells including a display electrode pair that is formed of a scan electrode and a sustain electrode, and a scan electrode driving circuit. The scan electrode driving circuit disposes a plurality of subfields having an initializing period, an address period, and a sustain period in one field, generates a decreasing down-ramp voltage in the initializing period, and generates a negative scan pulse voltage and applies it to the scan electrodes in the address period. In the initializing period, after the generation of the down-ramp voltage, the scan electrode driving circuit generates negative pulse voltage lower than the minimum voltage of the down-ramp voltage and applies it to the scan electrodes.
