Patent ID: 7112922

Claim:
A plasma display panel comprising: a scan electrode and a sustain electrode which are parallel with each other on a front substrate; a data electrode on a back substrate in a direction crossing the scan electrode and the sustain electrode, the back substrate facing the front substrate with a discharge space therebetween; a priming electrode on the back substrate parallel with the scan electrode and the sustain electrode; a first discharge space and a second discharge space on the back substrate and partitioned apart by a barrier rib; and an auxiliary electrode on an optical absorption layer which is between adjacent scan electrodes and connected to the scan electrode at a non-display portion, wherein the auxiliary electrode connected to the scan electrode is covered with a dielectric layer and a protective layer, the first discharge space is a main discharge space for performing a discharge with the scan electrode, the sustain electrode and the data electrode, and the second discharge space is a priming discharge space for performing a discharge with a positive voltage applied to the priming electrode in the address period between the priming electrode and the auxiliary electrode, and in the priming discharge space, a material layer comprising at least one material selected from the group consisting of alkali metal oxide, alkali metal fluoride, alkaline earth metal oxide, and alkaline earth metal fluoride, on a discharge space side of the priming electrode.
