Patent ID: 7385352

Claim:
A plasma display panel comprising: a rear substrate; address electrodes arranged at predetermined intervals over the rear substrate; a rear dielectric layer arranged to cover the address electrodes; barrier ribs arranged to partition discharge spaces on the rear dielectric layer; phosphor layers arranged in the discharge spaces; a front substrate arranged over the rear substrate and facing the rear substrate; sustain electrodes arranged orthogonal to the address electrodes and under the front substrate, a pair of the sustain electrodes including a common electrode and a scan electrode arranged within a discharge region corresponding to a discharge space so as to have a discharge gap therebetween; bus electrodes respectively connected to the sustain electrodes; a front dielectric layer arranged to cover the sustain electrodes and the bus electrodes; and at least one initial discharge inducing string, each string respectively arranged in discharge regions in the front dielectric layer, the at least one initial discharge inducing string comprising a dielectric material having a different dielectric constant from that of the front dielectric layer.
