Patent ID: 7372203

Claim:
A plasma display panel, comprising: a front substrate and a rear substrate which face each other and which 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 formed on the upper surface of the rear substrate to cover the address electrodes; a plurality of partition walls that are formed on an upper surface of the first dielectric layer and that partition the discharge space to form a plurality of discharge cells; a fluorescent layer formed on the upper surface of the first dielectric layer and on sidewalls of the partition walls forming inner surfaces of the discharge cells; first sustain electrodes and second sustain electrodes formed on a lower surface of the front substrate in each of the discharge cells in a direction perpendicular to the address electrodes, each of the first sustain electrodes and the second sustain electrodes comprising a plurality of electrodes; and a second dielectric layer covering the first sustain electrodes and the second sustain electrodes and formed on the lower surface of the front substrate, the second dielectric layer having a lower surface comprising horizontal surface portions which are parallel to the lower surface of the front substrate, each pair of horizontal surface portions being separated by a protruding portion, each protruding portion being centered on a line which is centered between the first sustain electrodes and the second sustain electrodes, each protruding portion extending away from said pair of horizontal surface portions so as to protrude into a respective one of the discharge cells; wherein a recess is formed in the first dielectric layer below each of the protruding portions of the second dielectric layer; and wherein the recess is formed to have a shape corresponding to said each of the protruding portions.
