    • PROBLEM TO BE SOLVED: To provide a plasma display device excellent in image display quality, which generates stable writing discharge without raising voltage necessary for generating the writing discharge even in the case of a large screen/high definition/high luminance panel. SOLUTION: A sustaining pulse generation circuit comprises: an electric power recovery part for applying voltage to a display electrode pair by resonance of static capacitance between the display electrode pair and inductance for power recovery; and a clamp part for clamping the display electrode pair to power source voltage or ground potential, and is configured so that at the end of the sustaining period, the circuit applies voltage to one of the display electrode pair using the electric power recovery part when a lighting rate is a prescribed threshold value or higher, to generate first discharge, thereafter, generates second discharge by switching to the clamp part and further applying voltage thereto, and when the lighting rate is lower than the prescribed threshold value, the circuit applies voltage to one of the display electrode pair using the electric power recovery part, and changes over to the clamp part before discharge is generated by the applied voltage to generate discharge by further applying the voltage thereto.
