Abstract
A PDP that can significantly improve light emitting efficiency and light transmission includes a new discharge cell structure and electromagnetic wave shielding electrodes that replace the function of an electromagnetic wave shielding filter includes: a transparent front substrate; a rear substrate arranged in parallel to the front substrate; a plurality of front barrier ribs, consisting of a dielectric material, and arranged between the front substrate and the rear substrate to define discharge cells together with the front substrate and the rear substrate; a front discharge electrode and a rear discharge electrode, separated from each other, and arranged in the front barrier rib to surround the discharge cell; at least one electromagnetic wave shielding electrode, arranged in front of and separated from the front discharge electrode, and surrounding the discharge cell; a plurality of rear barrier ribs arranged between the front barrier ribs and the rear substrate; a fluorescent layer arranged in a space defined by the rear barrier ribs; and a discharge gas arranged within the discharge cells.
