The invention discloses a plasma display device which comprises a plasma display screen, a scanning electrode, an addressing electrode, a maintaining electrode, a control circuit and a high-voltage drive circuit connected with the control circuit. The high-voltage drive circuit exerts the following driving waveforms to all the electrodes through the control circuit, wherein the driving waveforms include a reset period, an addressing period and a maintaining period. The reset period comprises a last persistent period, an ascending ramp voltage period and a descending ramp voltage period. The high-voltage drive circuit exerts a pulse waveform with the voltage being 40 V to 60 V and the width larger than 4 us on the addressing electrode at the last persistent period and the ascending ramp voltage period of the reset period. The plasma display device is obvious in effect, capable of protecting a product against influences and great in economic value.
