PURPOSE: To provide a plasma display driving method capable of reducing erroneous discharges in a dot matrix type AC plasma display having a memory function. CONSTITUTION: The distribution of effective voltages due to the superposition of residual charges and a scanning voltage is eliminated by making residual barrier charge amounts constant without depending on discharge characteristics for every cell while inserting a preliminary discharge erasing voltage holding time for 5 μs or more 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. Furthermore, residual barrier charges in cells in which writing discharge are not generated are eliminated by inserting an erase period before sustenance between a scanning period and a sustenance period and by inserting an erasing voltage holding time before sustenance for 5 μs or more after the potential change of the erasing voltage before sustenance whose potential change is gentle to reduce erroneous discharges due to the superposition with the scanning voltage.
