Patent ID: 7656091

Claim:
A plasma display panel comprising: a front substrate having sustain discharge electrodes; a rear substrate arranged parallel with the front substrate, the rear substrate having address electrodes crossing the sustain discharge electrodes; an upper dielectric layer covering the sustain discharge electrodes; a lower dielectric layer covering the address electrodes; a barrier rib located between the front substrate and the rear substrate, the barrier rib forming discharge spaces between the front substrate and the rear substrate and having a barrier rib central region and a barrier rib circumferential region, the barrier rib central region having a central region height and the barrier rib circumferential region having a circumferential region height, the central region height being greater than the circumferential region height; and a frit spaced along a circumference of the barrier rib to attach the rear substrate to the front substrate, wherein the circumferential region height satisfies the equation: 0.96H M <H E <0.98H M , wherein H M is the central region height, and H E is the circumferential region height.
