A plasma display device includes a plurality of sub fields, each sub field having an address period and a sustain period in which a sustain discharge is generated by applying a sustain pulse by the number of times corresponding to a brightness weight. A sustain pulse generating circuit has a power recovery section for raising or lowering the sustain pulse by allowing an inter-electrode capacitor of a display electrode pair including a scan electrode and a sustain electrode and an inductor to resonate and a clamp section for clamping a voltage of the sustain pulse to a predetermined voltage. The sustain pulse generating circuit sets a sustain pulse for generating a sustain discharge just before the final sustain discharge in the sustain period to a sustain pulse other than a sustain pulse having the shortest repetition period.
