The plasma display panel includes fluorophor layers containing magnesium oxide. The drive method includes a reset step to initialize all the 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, which are successively executed in each of a head subfield and a second subfield within a one-field display period. In reset step, a voltage that sets row electrodes on one side, in the row electrode pairs as an anode and sets the column electrodes set as a cathode is applied between the row electrodes on the one side and the column electrodes.

Abstract: A plasma display panel has a front substrate, a rear substrate, and a phosphor layer. The front substrate has a dielectric layer formed so as to cover a plurality of display electrodes disposed on a substrate, and a protective layer formed on the dielectric layer. The rear substrate is faced to the front substrate so as to form discharge space, has data electrodes in the direction intersecting with the display electrodes, and has barrier ribs for partitioning the discharge space. The phosphor layer is formed by applying phosphor ink that is made of a phosphor material and dispersant between the barrier ribs of the rear substrate. Nano-particles with a diameter of a range of 1 nm to 100 nm inclusive, or a solvent having an affinity for the dispersant of the phosphor ink is applied to the surfaces of the barrier ribs, and then the phosphor ink is applied to them, thereby forming the phosphor layer.
