Patent ID: 7595589

Claim:
A plasma display panel (PDP), comprising: a lower substrate and an upper substrate arranged opposite to each other and spaced apart from each other, a discharge space being arranged between the lower substrate and the upper substrate; a plurality of partitions arranged between the lower substrate and the upper substrate, the partitions adapted to partition the discharge space into a plurality of discharge cells; a plurality of address electrodes arranged on an upper surface of the lower substrate; a first dielectric layer covering the plurality of address electrodes; a plurality of first sustain electrodes arranged between the upper substrate and the lower substrate, the first sustain electrodes including closed loops, each closed loop corresponding to individual discharge cells; a plurality of second sustain electrodes arranged between the upper substrate and the lower substrate and including closed loops, each closed loop corresponding to closed loops of the first sustain electrodes; a phosphor layer arranged on an upper surface of the first dielectric layer and on sidewalls of the partitions; and a protrusion of a dielectric material extending from the upper surface of the first dielectric layer into each of the plurality of discharge cells, the second sustain electrodes being arranged on upper surfaces of each protrusion.
