Disclosed are a plasma display apparatus and a driving method thereof. The plasma display apparatus comprise a plasma display panel having a scan electrode and a sustain electrode, a scan driver for sequentially supplying a first rising ramp waveform, a first falling ramp waveform and a second falling ramp waveform to the scan electrode during the reset period of the first subfield of a plurality of subfields, and a sustain driver for supplying a round waveform to the sustain electrode while the first rising ramp waveform is being supplied to the scan electrode. In the driving method of a plasma display apparatus, which divides a plurality of subfields with a different number of times of light emission into a rest period, an address period and a sustain period, and displays an image by applying a signal to the scan electrode, sustain electrode and address electrode in the respective periods, a surface discharge occurs two times between the scan electrode and the sustain electrode in the reset period of the first subfield of the plurality of subfields, and an opposite discharge occurs between the scan electrode and the address electrode.
