A plasma display panel and driving method thereof perform addressing at a high speed and a low voltage without deteriorating contrast. Priming electrodes forming priming cells are located outside but adjacent a display area. Glow occurring in the priming cells is intercepted. When priming discharge is induced at a reset step, voltages lower than a discharge start voltage are applied to first (X) and second (Y) electrodes and third (address) electrodes respectively. Despite the voltages being lower than the discharge start voltage, once discharge is induced in the priming cells, discharge starts in adjoining cells. The discharge then spreads successively over all the cells, thus inducing discharge in all the cells. Consequently, wall charge is produced in all the cells.
