Patent ID: 7755288

Claim:
A plasma display panel comprising: a first substrate; a plurality of sustain electrodes on the first substrate, each of the sustain electrodes being composed of an X electrode and a Y electrode; a first dielectric layer covering the sustain electrodes; a protective layer on the first dielectric layer; a second substrate facing the first substrate; a plurality of address electrodes on the second substrate and crossing the sustain electrodes; a second dielectric layer covering the address electrodes; and a plurality of barrier ribs between the first substrate and the second substrate to define a plurality of discharge cells; and a phosphor layer at the discharge cells, wherein the sustain electrodes are located to correspond to a first region of the protective layer, wherein the first region of the protective layer is greater in thickness than a second region of the protective layer, and wherein the first region of the protective layer is formed of an identical material as that of the second region of the protective layer.
