A Plasma Display Panel (PDP) having improved brightness and discharge efficiency includes: a first substrate and a second substrate separated from each other; barrier ribs disposed between the first substrate and the second substrate and defining a plurality of discharge cells together with the first substrate and the second substrate; a plurality of first electrodes and a plurality of second electrodes disposed in the barrier ribs and extending in a first direction parallel to each other; a plurality of address electrodes disposed in the barrier ribs and extending in a second direction intersecting the first direction; a plurality of phosphor layers disposed in the discharge cells; and a discharge gas contained within the discharge cells. A unit frame is divided into a plurality of subfields having corresponding gray-scale weights for gray-scale display, each subfield is divided into a reset period in which the discharge cells are initialized, an address period in which discharge cells to be turned on are selected, and a sustain period in which a sustain discharge corresponding to the gray-scale weights occurs in the selected discharge cells, and in the sustain period, either a sustain pulse alternately having a first voltage with positive polarity and a second voltage lower than the first voltage is alternately supplied to the first electrodes and the second electrodes, and a third voltage with positive polarity is supplied to the address electrodes, or the address electrodes are floating.
