Abstract
A high performance surface discharge type PDP includes a first glass substrate having a plurality of scanning electrode pairs (X, Y) in parallel with each other and black stripes in parallel with the scanning electrode pairs formed on one main surface thereof and having a dielectric layer covering them. The PDP further includes a second glass substrate including a plurality of address electrodes W formed in parallel with each other in a direction orthogonal to the scanning electrode pairs and having a plurality of barrier ribs in parallel with the address electrodes W for abutting the dielectric layer to form discharge spaces corresponding to each of the address electrodes W. The black stripes formed on the first glass substrate have portions that each intersect with a top of a corresponding one of the plurality of barrier ribs on the second glass substrate which are cut into pieces. Consequently, clearances can be reduced in a portion where the top of the barrier rib abuts the dielectric layer, thereby narrowing an unnecessary discharge space between adjacent unit luminescent areas EU, and less defective writing results from an erroneous discharge or the like.
