A driving method of plasma display panels is disclosed. This method can suppress a dark belt occurring in displaying a video of a lower part of grayscale. One field includes plural sub-fields, and each one of the sub-fields has an addressing period during which a scan pulse is applied to the scan electrodes and a data pulse is applied to the data electrodes, and a sustaining period during which a sustain pulse is applied to the scan electrodes and the sustain electrodes. A time interval between a scan pulse applied lastly during the addressing period and a sustain pulse applied firstly during the sustaining period is defined as a last pulse-interval. The last pulse-interval of at least one sub-field of a lower part of grayscale, which lower part is darker than a predetermined level of the grayscale, is set longer than the last pulse-intervals of the other sub-fields.
