Abstract
A method for driving an AC type plasma display panel is provided in which time necessary for addressing can be shortened without deteriorating stability of a display. Before the addressing, a reset process is performed by applying an increasing waveform voltage between a reference potential line and a scan electrode so as to equalize charge in all cells. In the addressing, a selection voltage Vya having the same polarity as a final applied voltage Vyr in the reset process and an absolute value larger than the voltage Vyr by a potential difference &Dgr;Vy is applied between a scan electrode corresponding to a selected row and the reference potential line.
