A method of driving a plasma display panel (PDP) and a plasma display device driven by the method are disclosed. In one embodiment, a display image is represented by a plurality of unit frames, and each unit frame is divided into a plurality of sub-fields. Each of the sub-fields includes a reset period when all discharge cells are initialized, an address period when a discharge cell that is turned on or off is selected from all discharge cells, and a sustain period when a sustain discharge is performed for a discharge cell selected to be turned on in the address period according to gray-level weights allocated to each of the sub-fields. Furthermore, a rising ramp pulse and a falling ramp pulse are applied to the first electrode in the reset period. According to one embodiment of the invention, reset light generated by a reset discharge can be minimized in a reset period, and wall charges in discharge cells can be precisely controlled so that light-emitting efficiency is improved and the likelihood of a permanent afterimage being left on the display is reduced.
