A method for driving a plasma display panel having front and rear substrates opposed to and facing each other, X and Y electrode lines between the front and rear substrates parallel to each other and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections. A scan pulse is applied to the respective Y electrode lines with a predetermined time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to form wall charges at pixels for a display discharge and pluses for a display discharge are alternately applied to the X and Y electrode lines to cause a display discharge at the pixels where the wall charges have been formed. Here, the scan pulse is progressively applied to the corresponding Y electrode lines of subfields established as driving periods for a time-division gray scale display, and the scanning order for the subfields changes according to the field, which is a unit display period.
