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 drive circuit having a sustain pulse generation circuit. A first ramp waveform voltage that rises gradually is generated in an initialization period of at least one sub-field of a single field period; and a second ramp waveform voltage which has a gradient sharper than that of the first ramp waveform voltage and falls immediately after a rising waveform voltage reaches a predetermined prescribed potential is generated in the last of a sustain period; a first sustain pulse which is at least a reference and a second sustain pulse which rises more quickly than the first sustain pulse are generated by switching, and the second sustain pulse is applied continuously to an electrode to which the second ramp waveform voltage will be applied; and a prescribed number of times corresponding to the total number of sustain pulses in the sustain period, immediately before the second ramp waveform voltage, is applied sequentially.
