PROBLEM TO BE SOLVED: To stably generate a write discharge in a plasma display panel. SOLUTION: A plasma display device is equipped with the plasma display panel and a driving circuit having a sustain pulse generation circuit, and the driving circuit generates a first inclined waveform voltage which gently rises in an initialization period of at least one sub-field in a one-field period and also generates a second inclined waveform voltage, which has its gradient made steeper than the first inclined waveform voltage and falls immediately after the rising waveform voltage reaches a predetermined potential, in the ending of a sustain period to alternately generate at least a first reference sustain pulse to be a reference and a second sustain pulse which rises more steeply than the first sustain pulse and falls more gently than the first sustain pulse, the second sustain pulse being applied to an electrode to be applied with the second inclined waveform voltage only predetermined times right before the second inclined waveform voltage.
