In a surface-discharge-type alternating-current plasma display panel, a discharge cell is divided into two cells: a display discharge cell C1 providing for a sustaining discharge between transparent electrodes Xa, Ya of row electrodes X, Y; and an addressing discharge cell C2 which is opposite a bus electrode Yb of the row electrode Y, giving rise to an addressing discharge in association with a column electrode D, to provide for the addressing discharge between the bus electrode Yb of the row electrode Y and a column electrode D. The display discharge cells C1 and the addressing discharge cells C2 of the discharge cells are interposed in alternate positions in the column direction so as to arrange the addressing discharge cells C2 in a back-to-back position in the column direction.
