A plasma display panel of an AC 3-electrode plane discharge type includes a front substrate and a back substrate. A plurality of sets of plane discharge electrodes are formed on the front substrate to extend to a row direction, and a plurality of address electrodes formed on the back substrate to extend a column direction. A plurality of row separation walls are formed on the back substrate and the plurality of address electrodes to extend in the row direction, and a plurality of column separation walls are formed on the back substrate to extend in the column direction. A plurality of discharge cells are arranged in matrix. Each of the plurality of discharge cells is defined by adjacent two of the plurality of row separation walls and adjacent two of the plurality of column separation walls, and each of rows of the plurality of discharge cells is associated with one of the plurality of sets of plane discharge electrodes and each of columns of the plurality of discharge cells is associated with one of the plurality of address electrodes. Each of the plurality of sets contains a first plane discharge electrode and a second plane discharge electrode. The first plane discharge electrode is provided above a corresponding one of the plurality of row separation walls and a corresponding one of the rows of the plurality of discharge cells, and the second plane discharge electrode is provided above the corresponding one of the rows of the plurality of discharge cells.
