A plasma display apparatus is provided to enhance the performance of the plasma display apparatus by elongating gradually the sustain interval of a sustain voltage during a sustain period of one sustain field. A plasma display apparatus includes a plasma display panel(100), sustain and data drivers(110,120), and a reference separation controller(130). The plasma display panel includes first and second electrodes, and third electrodes to cross with the first and second electrodes. The sustain driver supplies a first sustain pulse which has a first sustain interval to maintain a positive sustain voltage and a second sustain interval to maintain a negative sustain voltage, and a second sustain pulse which has a third sustain interval to maintain a positive sustain voltage and a fourth sustain interval to maintain a negative sustain voltage, to the first electrodes and supplies a reference voltage to the second electrodes. The data driver supplies data pulses to the third electrodes. The reference separation controller controls the sustain driver, a first reference voltage source connected to the second electrodes, and a second reference voltage source connected to the data driver.
