PROBLEM TO BE SOLVED: To stably generate a write discharge in a plasma display panel. SOLUTION: A plasma display device includes a panel temperature detection circuit which detects a temperature of the plasma display panel, and a driving circuit generates a first ramped waveform voltage, slowly rising in an initialization period of at least one sub-field of one field period and generates a second ramped waveform voltage, which has a gradient sharper than that of the first ramped waveform voltage and falls immediately after a rising waveform voltage reaches a preliminarily determined prescribed potential, in the last of a sustain period and provides a period when a pair of display electrodes are set to a base potential together, between the first generated sustain pulse and the second generated sustain pulse in a sustain period when the total number of sustain pulses in the sustain period except the second ramped waveform voltage is 2, and the period when the pair of display electrodes are set to the base potential together is changed in accordance with the temperature detected by the panel temperature detection circuit.
