PURPOSE: A plasma display panel device is provided to prevent a rise of discharge voltage and erroneous discharge caused due to a temperature rise. CONSTITUTION: A plasma display panel device comprises a lower substrate on which an address electrode(10) is formed; and an upper substrate on which a transparent electrode(20) and a bus electrode(30) are formed. The lower substrate and the upper substrate are spaced apart from each other. The address electrode is arranged to have a width gradually increasing along the sequence of driving of a scan line electrode. Alternatively, the spacing between the bus electrodes gradually decreases along the sequence of driving of the scan line electrode.
