Abstract

A plasma display panel includes a lower substrate and an upper substrate facing each other. A plurality of barrier ribs is arranged between the lower substrate and the upper substrate and partitions the discharge space to form a plurality of discharge cells. First and second sustaining electrodes are formed as pairs in the discharge cells on the upper substrate, and third and fourth sustaining electrodes, which are arranged in the barrier ribs, are formed as pairs facing each other in the discharge cells. A surface discharge occurs between the first and second sustaining electrodes, and a facing discharge occurs between the third and fourth sustaining electrodes.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly, to a PDP with reduced discharge voltage and improved luminous efficiency. Background technique [0002] Generally, a plasma display panel (PDP) forms images using electric charge discharge. Excellent performance in terms of brightness and viewing angles has ensured its popularity. In the PDP, applying direct voltage (DC) or alternating voltage (AC) to electrodes discharges gas between the electrodes, thereby generating ultraviolet rays that excite fluorescent materials that emit visible light to form images. [0003] According to the discharge cell structure, the PDP may be a DC type PDP or an AC type PDP. A direct current type PDP has a structure in which all electrodes are exposed to a discharge space and charges directly move between the electrodes. The AC type PDP has a structure in which at least one electrode is covered with a dielectric layer and charges do ...
