Abstract
A plasma display apparatus is disclosed. The plasma display apparatus includes a plasma display panel including first, second and third electrodes and a sustain driver. The sustain driver supplies a sustain signal swinging between a positive sustain voltage and a negative sustain voltage to the first electrode. The sustain driver supplies a voltage gradually falling from the positive sustain voltage or a voltage gradually rising from the negative sustain voltage to the first electrode during a second period following a first period when the positive sustain voltage or the negative sustain voltage is supplied. The sustain driver includes an inductor into which a current flows in the same direction during the first period and the second period.
