Patent ID: 8237362

Claim:
A plasma display panel comprising: a first substrate; a second substrate facing the first substrate; a plurality of sustain electrode pairs between the first substrate and the second substrate and extending in a first direction; a plurality of address electrodes on the second substrate and extending in a second direction crossing the first direction of the sustain electrode pairs; a first dielectric layer on the second substrate for covering the plurality of address electrodes; a discharge enhancement layer on the first dielectric layer; a plurality of barrier ribs on the discharge enhancement layer, and defining discharge cells between the first substrate and the second substrate; and phosphor layers in the discharge cells and being in contact with a topmost surface of the discharge enhancement layer, the topmost surface facing oppositely away from the second substrate, wherein the discharge enhancement layer has an opening in each of the discharge cells, and wherein the barrier ribs have a roughness less than that of the discharge enhancement layer.
