PURPOSE: A plasma display panel and its driving method are provided to improve a driving voltage margin in a process for driving the plasma display panel by changing continuously supply voltage values to the positive direction and the negative direction. CONSTITUTION: A plasma display panel includes a first substrate having a first electrode and a second electrode and a second substrate having a third. An image of the first frame is composed of subfields of n number. In a reset period, an erase discharge process is performed in each subfield. In an address period, A process for distributing walls charges is performed according to display data. In a sustain discharge period, a sustain discharge process is performed by applying sustain discharge pulses, repeatedly. In the reset period, a first process for applying fine pulses less than 2 micrometers, a second process for applying erase pulses to change continuously supply voltage values to the positive direction, and a third process for applying the erase pulses to change continuously the supply voltage values to the negative direction.
