A plasma display device includes a sustain pulse generating circuit having a power recovery section for raising or lowering the sustain pulse by allowing an inductor and an inter-electrode capacitor of the display electrode pair to resonate and a clamp section for clamping a voltage of the sustain pulse to a predetermined voltage. The sustain pulse generating circuit sets the sustain pulse generated in the sustain period so as to include sustain pulses in which the lengths of time for raising the sustain pulses using the power recovery section are different from each other, and sets the sustain pulse for generating the final sustain discharge in the sustain period to a sustain pulse other than a sustain pulse in which the length of time for raising the sustain pulse is the longest.
