Patent ID: 8681076

Claim:
A plasma display panel comprising: a front substrate; a plurality of electrodes arranged on the front substrate; an upper dielectric layer coveting the plurality of electrodes on the front substrate; and a rear substrate arranged opposite to the front substrate, wherein the upper dielectric layer comprises a convex portion thicker than a surrounding portion thereof and a concave portion thinner than a surrounding portion thereof, and a middle portion positioned between the convex portion and the concave portion, wherein the convex and concave portions have uniform thickness, wherein a thickness of the middle portion gradually increases from the concave portion to the convex portion, wherein the electrodes includes a scan electrode and a sustain electrode, wherein the scan electrodes and the sustain electrodes are arranged in the order of the scan electrode, the scan electrode, the sustain electrode and the sustain electrode, wherein the concave portion is located between the scan electrode and the sustain electrode, wherein the middle portion is partially overlapped with the scan electrode or the sustain electrode in a vertical direction with respect to the front substrate, wherein two scan electrodes or the two sustain electrodes are partially overlapped with the single convex portion in the vertical direction, and wherein the concave portion is not overlapped with the scan electrode and the sustain electrode.
