An AC-type PDP in which adjacent two scanning lines share one sustain discharge electrode and a discharge separator for separating surface discharges in the adjacent scanning lines is driven as follows. In a writing period (O4), the voltages at odd-numbered sustain discharge electrodes (J2n-1) are set to the voltage (H) and the voltages at even-numbered sustain discharge electrodes (J2n) are set to the voltage (M). At selection of odd-numbered scanning lines (S2n-1) in descending order, when image data (W) according to the scanning line (S2n-1) is applied to an address electrode (22), the voltages at the sustain discharge electrodes (J2n+1 and J2n) are changed to the voltages (M and L), respectively. In a polarity reverse period (RV), after a voltage (Voff) is applied to all the address electrodes (22) and the voltages at the sustain discharge electrodes (J2n-1 and J2n) are changed from the voltage (M) to the voltages (L and H), respectively, the voltages at the sustain discharge electrodes (J2n-1 and J2n) are returned to the voltage (M). In a writing period (E4), even-numbered scanning lines (S2n) are selected in ascending order conversely to the order in the writing period (O4). With this operation, it is possible to enhance a display contrast, reduce a reactive power and stabilize a writing discharge.
