PROBLEM TO BE SOLVED: To reduce erroneous discharges in a dot matrix type AC plasma display device having a memory function. SOLUTION: The distribution of effective voltages due to the superposition of residual barrier charges and a scanning voltage is eliminated by making residual barrier charge amounts constant without depending on discharge characteristics for every cell while inserting preliminary discharge erasing voltage holding time for≥5μs after the potential change of a preliminary discharge erasing pulse to reduce erroneous discharge. Moreover, it is made possible to reduce a data voltage and the scanning voltage by the superposition of a residual barrier charge corresponding to the potential difference between the final ultimate voltage of the preliminary discharge erasing pulse and a scanning pulse voltage while making the scanning pulse voltage larger than the final ultimate voltage of the preliminary discharge erasing pulse and the scanning voltage.
