    Abstract: Even in a plasma display panel of large screen size and high definition, address discharge is caused stably. A plasma display device has a plasma display panel and a scan electrode driving circuit. The plasma display panel includes a discharge cell having a display electrode pair that is formed of a scan electrode and a sustain electrode. A plurality of subfields having an initializing period, an address period, and a sustain period are disposed in one field period. The scan electrode driving circuit generates an increasing first ramp voltage in the initializing period of at least one subfield in one field period, generates sustain pulse voltage that varies from a base potential to a potential for causing sustain discharge in the sustain period, and generates second ramp voltage that is increased and is dropped immediately after reaching a predetermined potential at the end of the sustain period.
