A plasma display device and driving method thereof are disclosed. In the plasma display device, a wall charge state of each cell is initialized after forming a wall voltage between respective sustain electrodes by gradually decreasing a voltage of the sustain electrodes. In addition, in a sustain period, a high level sustain discharge pulse having a positive voltage and a low level sustain discharge pulse having a negative voltage are applied to the sustain electrode while maintaining a voltage of a scan electrode at a ground voltage. In this way, a maximum voltage applied to a scan electrode driver that applies the driving waveform to the scan electrode is decreased. In addition, a sustain discharge pulse is applied only to the sustain electrode, which is a common electrode, and therefore the driving waveform between each cell can be prevented from being distorted in the sustain period.
