A plasma display panel and a drive method therefor, which can enhance a representation capability when displaying a dark image. The plasma display panel includes fluorophor layers (17) which are respectively disposed at positions confronting the discharge cells, wherein a discharge gas is enclosed in the discharge space, and magnesium oxide (17B) is contained in the fluorophor layers. A drive method of a plasma display panel pixel cells that contain fluorophor materials and a secondary electron emission material, includes a reset step in which all the pixel cells are caused to perform reset discharges, thereby to initialize the individual pixel cells into states of one of a light-up mode and a light-off mode, and an address step in which the pixel cells are caused to perform address discharges selectively in accordance with pixel data, thereby to shift the individual pixel cells into states of the other of the light-up mode and the light-off mode, are successively executed in each of a head subfield and a second subfield within a one-field display period. In each reset step, a voltage with row electrodes on one side, in the row electrode pairs set as an anode side and the column electrodes set as a cathode side is applied between the row electrodes on one side and the column electrodes, whereby the reset discharges are induced between both the electrodes. In another aspect, in a head subfield within a one-field display period, a voltage with row electrodes on one side, in the row electrode pairs set as an anode side and the column electrodes set as a cathode side is applied between the row electrodes on one side and the column electrodes, whereby reset discharges for initializing all the pixel cells into a light-off mode are induced between the column electrodes and the row electrodes within all the pixel cells.
