Abstract
A plasma display panel includes a front plate having a dielectric layer covering a display electrode formed on a substrate and a protective layer formed on the dielectric layer, and a rear plate facing the front plate so as to form a discharge space. The plasma display panel also includes an address electrode in a direction crossing the display electrode, barrier ribs for partitioning the discharge space, and phosphor layers. The protective layer is constructed by forming a ground film on the dielectric layer and adhering agglomerated particles to the ground film. The agglomerated particles are produced by coagulating a plurality of crystal particles made of metal oxide.
