    • A displaying method of a plasma display device is provided to prevent image deterioration like a display defect even though the peak brightness is high. A plurality of scan electrodes and sustain electrodes are extended in the same direction. The scan electrodes and the sustain electrodes are arranged adjacently. A plasma display panel(11) includes a plurality of address electrodes extended in a direction perpendicular to the plurality of scan electrodes and sustain electrodes.
