ABSTRACT:
A plasma display panel (PDP) includes a front panel, a rear panel disposed parallel to the front panel, first barrier ribs formed of a dielectric substance and disposed between the front panel and the rear panel to define a plurality of discharge cells, front discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells and spaced from the side surfaces of the discharge cells toward interiors of the first barrier ribs by an electrode-burying depth, rear discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells and spaced from the side surfaces of the discharge cells toward the interiors of the first barrier ribs by an electrode-burying depth at the rear side of the first discharge electrodes, a plurality of phosphor layers disposed inside the discharge cells for receiving ultraviolet rays and emitting visible rays, the phosphor layers having different dielectric constants, and a discharge gas filling the discharge cells. The electrode-burying depth corresponding to discharge cells in which phosphor layers having the lowest dielectric constant are formed is smaller than the electrode-burying depth corresponding to discharge cells in which phosphor layers having a relatively high dielectric constant are formed.
