A plasma display apparatus is disclosed. The plasma display apparatus includes a first driver, a third driver, and a separation controller. The first driver supplies a driving signal to a first electrode of a plasma display panel during a reset period, an address period and a sustain period and is electrically connected to a first reference voltage source. The third driver supplies a data signal to a third electrode of the plasma display panel during the address period and is electrically connected to a second reference voltage source. The separation controller controls the electrical separation between the first reference voltage source and the second reference voltage source during at least one period of the reset period, the address period or the sustain period.
