Abstract

A Plasma Display Panel (PDP) has a high aperture ratio of a discharge cell, a high light transmittance, and a high luminous efficiency and a stable and efficient discharge occurs uniformly at a low driving voltage on inner sidewalls of the discharge cell and concentrates in the center of the discharge cell. The PDP includes: a front substrate and a rear substrate facing each other and separated from each other; barrier ribs of a dielectric material arranged between the front substrate and the rear substrate to define discharge cells together with the front substrate and the rear substrate; discharge electrodes arranged within the barrier ribs, the discharge electrodes being separated from each other and surrounding the discharge cells and having at least one corner portion for surrounding the discharge cells; fluorescent layers arranged in the discharge cells; a discharge gas contained within the discharge cells; and an attenuator adapted to reduce a strength of an electric field generated between at least one pair of corner portions of the discharge electrodes, the corner portions facing each other, to be less than a strength of an electric field generated between portions of the discharge electrodes facing each other, other than the corner portions, in the discharge cells.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly to a PDP having a high discharge cell aperture ratio, high light transmittance and high luminous efficiency, wherein stable and efficient discharge occurs uniformly at a low driving voltage On the side wall of the discharge chamber, and concentrated in the middle of the discharge chamber. Background technique [0002] In an AC three-pole type surface discharge PDP, the PDP includes a front panel and a rear panel. The front panel includes a front substrate, a pair of sustain electrodes consisting of X electrodes and Y electrodes on the rear surface of the front substrate, a front dielectric layer covering the sustain electrodes, and a protective layer covering the front dielectric layer. Each Y electrode includes a transparent electrode and a bus electrode, and each X electrode includes a transparent electrode and a bus electrode. The transparen...
