Abstract

The PDP has a front panel, and has a back panel with address electrodes formed thereon. Front panel has display electrodes including first electrodes and second electrodes formed on a front glass substrate, and a dielectric layer covering display electrodes. Further, the first electrodes and the dielectric layer include glass frit, which contains at least one of molybdenum oxide, magnesium oxide and cerium oxide, and also include a softening point exceeding 550° C. The above-described makeup suppresses a coloring phenomenon in the dielectric layer and the front glass substrate, thereby implementing a plasma display panel with a high luminance.
