Abstract
Sustain discharge is stably caused while power consumption is reduced, and image display quality is improved. A plasma display device has a plasma display panel, an electric power recovering circuit for raising or falling a sustain pulse by resonating an inductor and the inter-electrode capacity of a display electrode pair, and a sustain pulse generating circuit for alternately applying, to the display electrode pair, as many sustain pulses as the number corresponding to the luminance weight in the sustain period of a plurality of subfields that are disposed in one field and have initializing, address, and sustain periods. The sustain pulse generating circuit generates at least two kinds of sustain pulses including a first sustain pulse serving as a reference and a second sustain pulse that rises more gently than the first sustain pulse, and generates the first sustain pulse immediately after the second sustain pulse.
