ABSTRACT:
The present invention provides a plasma display device including: a plurality of scan electrodes sequentially scanned to be impressed with a scan pulse; an address electrode that is impressed with an address pulse corresponding to the scan pulse, for selection of a display pixel; a scan driving circuit generating the scan pulse; and an address driving circuit generating the address pulse. The address pulse rises in n stages (n is an integer equal to or larger than 2), and a period in a period during which the address pulse rises from a lowest voltage to a highest voltage overlaps a scan pulse immediately prior to the scan pulse corresponding to the address pulse.
