Plasma Display Device

A driving method of a plasma display panel which performs image display using a plurality of sub-fields. In a sustain discharge period, a first sustain discharge waveform and a second sustain discharge waveform are applied, the second sustain discharge waveform having a timing of voltage clamping at a rising edge of a pulse which is earlier than that of the first sustain discharge waveform. In a predetermined sub-field in one frame, the first sustain discharge waveform is repeatedly applied without applying the second sustain discharge waveform, and in other sub-fields, the first sustain discharge waveform and the second sustain discharge waveform are repeatedly applied.
