PROBLEM TO BE SOLVED: To prevent residual charges from being generated and to enable stable address discharging without causing any increase in power consumption by making the potential difference between electrodes at the time of reset discharging opposite in polarity from the potential difference between the electrodes at the time of selective discharging by the electrodes in an address period. SOLUTION: In an entire-surface writing process, a voltage of, for example, -120V is applied to a maintenance electrode X1 and a voltage of 180V is applied to a scanning electrode Y1 . Consequently, wall charges are generated on the respective electrodes. Then the voltages in the entire-surface writing process are made opposite in application polarity. Consequently, the wall surfaces accumulated on the maintenance electrodes X1 and scanning electrode Y1 are opposite in polarity from each other. In an address process, remaining wall charges having such a polarity that they are added to an address voltage applied between electrodes A1 and Y1 . Therefore, the voltage applied between the electrodes A1 and Y1 is never lowered under the influence of the residual charges and the address discharging can stably be performed.
