Patent ID: 7504777

Claim:
A plasma display panel, comprising: an upper substrate and a lower substrate facing each other; a plurality of barrier ribs disposed between the upper substrate and the lower substrate to define a plurality of discharge cells together with the upper substrate and the lower substrate; at least one pair of discharge electrodes that generate a discharge and extend across the discharge cells consecutively disposed in one direction; a plurality of address electrodes consecutively disposed to cross the discharge electrodes; an upper dielectric layer and a lower dielectric layer, respectively, covering the at least one pair of discharge electrodes and the plurality of address electrodes; a fluorescent layer disposed in the discharge cells; a discharge gas filled in the discharge cells, wherein each discharge electrode includes first, second and third electrodes which have substantially the same length, wherein the first electrode is closer to the center area of a respective discharge cell than the third electrode, wherein the second electrode is located between the first and third electrodes, and wherein the second electrode comprises a plurality of first substantially semi-circular concave portions each of which is formed in a direction generally facing the center area of the respective discharge cell; and a plurality of connecting electrodes each connecting electrode formed across the discharge cells and extending from the first electrode to the third electrode through generally the center area of each respective concave portion.
