Patent ID: 7265492

Claim:
A plasma display panel, comprising: front and rear substrates facing each other to form a discharge space therebetween; a plurality of address electrodes arranged in stripes on an upper surface of the rear substrate; a first dielectric layer arranged to cover the address electrodes on the upper surface of the rear substrate; partitions arranged on an upper surface of the first dielectric layer to partition the discharge space into a plurality of discharge cells; a plurality of second dielectric layers extending in a direction perpendicular to the address electrodes, each of the second dielectric layers protruding from a lower surface of the front substrate, each discharge cell being partially bounded by two sides of second dielectric layers, said two sides of the second dielectric layers being concavely curved; a first and a second sustaining electrodes arranged over the second dielectric layer in each discharge cell to be slanted to face each other; a third dielectric layer arranged over a lower surface of the second dielectric layers to cover the first and second sustaining electrodes, wherein a trench perforates the second dielectric layers and runs between adjacent ones of said plurality of discharge cells and being arranged in a direction perpendicular to the front substrate; and a black stripe arranged on a bottom surface of the trench.
