Abstract: The plasma display device has a sustain pulse generating circuit for generating sustain pulses in a sustain period. The sustain pulse generating circuit generates at least two kinds of sustain pulses of different rising gradients in the sustain period, generates a predetermined number of sustain pulse whose rising gradient becomes steeper to the latter half in at least one-side electrode in the sustain period after first two sustain pulses and except an erasing pulse, and continuously generates the sustain pulses while the rising gradient of the sustain pulses is varied in response to the light emitting rate of the plasma display panel in the sustain period.
