A plasma display apparatus and a driving method thereof are provided to form sufficient wall charges on cells of the plasma display apparatus by using a voltage difference formed between scan and sustain electrodes during a setup period. A plasma display panel includes plural scan and sustain electrodes. Plural drivers(311a,311b) supply a driving voltage to respective scan electrodes. A first voltage source(Vsource) supplies a first voltage to the drivers during a reset period and the first voltage through drivers connected to scan electrodes, which not receive a scan pulse during an address period. A second voltage supplying unit(312) supplies a second voltage for generating a scan ramp pulse during the reset period through the drivers. A third voltage supplying unit(313) supplies a third voltage for the scan pulse through drivers connected to scan electrodes, which not receive the first voltage during the address period. A reference voltage supplying unit(317) supplies a reference voltage to the scan electrodes through the drivers.
