A plasma display panel (PDP) is a display device which excites a fluorescent layer by using an ultraviolet ray of plasma and displays an image by using a visible light generated from the fluorescent layer. In a plasma display panel, a plurality of discharge cells are arranged in a matrix, and the discharge cells are selectively illuminated to restore image data, which are input as electrical signals. A plasma display device additively mixes three primary colors to give a full-color display by means of a phosphor layer that emits light in three primary colors: red (R), green (G), and blue (B). The use of plasma display panels is consequently becoming more widespread in recent years in the fields of large public display devices and in color television because plasma display devices have the advantages of being large, thin, and lightweight. The plasma display device falls roughly into an alternating current (AC) plasma display device and a direct current (DC) plasma display device according to its operation principle. A plasma display panel is provided with a plurality of scan electrodes, and sustain electrodes extending in the horizontal direction, and a plurality of data electrodes extending in the vertical direction. To display color images, a plasma display device generally produces ultraviolet rays through gas discharging for exciting phosphors. Ultraviolet rays generated in discharge cells of the PDP excite the phosphor particles constituting this phosphor layer such that they emit visible light of each color.
