A stable address discharge is caused to enhance the image display quality. For this purpose, a plasma display panel, a scan electrode driving circuit, and a partial light-emitting rate detecting circuit are provided. The scan electrode driving circuit performs an address operation by applying a scan pulse to scan electrodes in address periods. The partial light-emitting rate detecting circuit divides the display area of the plasma display panel into a plurality of regions, and detects a rate of the number of discharge cells to be lit with respect to the number of all the discharge cells in each region, as a partial light-emitting rate, in each subfield. In a predetermined subfield where the number of sustain pulses is smaller than the number of sustain pulses in the immediately preceding subfield, the scan electrode driving circuit changes the order of applying the scan pulse to the scan electrodes, according to the partial light-emitting rates in the immediately preceding subfield.
