PROBLEM TO BE SOLVED: To improve display quality and luminous efficiency in a plasma display panel. SOLUTION: A plasma display device has a plasma display panel which is provided with a plurality of discharge cells having a display electrode pair composed of a scan electrode and a sustain electrode, and a sustaining pulse generating circuit which applies a sustaining pulse to each of the display electrode pair using a power recovery circuit which causes rising or falling edge of the sustaining pulse by resonating inter-electrode capacitance and inductor of the display electrode pair and a clamp circuit which clamps a voltage of the sustaining pulse to a power source voltage or base potential. The sustaining pulse generating circuit generates sustaining pulses, wherein a time point of starting of a rising edge of the sustaining pulse applied to one electrode of the display electrode pair and a time point of starting of falling edge of the sustaining pulse applied to another electrode coincide each other, and the time of rising of the sustaining pulse applied to one electrode of the display electrode pair, and the time of the falling of edge of the sustaining pulse applied to another electrode are different.
