Patent ID: 7348729

Claim:
A plasma display panel in which a first panel and a second panel face each other with a spacing member sandwiched there between, a plurality of electrodes being disposed in stripes on one of the first and second panels, and a dielectric layer and a protective layer being layered in a stated order so as to cover the plurality of electrodes, wherein the protective layer includes a first layer made of seed crystals and a second layer made of a plurality of columnar crystals, the plurality of columnar crystals growing on the seed crystals, wherein the columnar crystals are MgO and the first layer includes an element selected from a first element group consisting of Ag, Al, Au, Be, Cd, Co, Cu, Ga, Hf, In, Ir, Ni, Os, Pd, Pt, Re, Rh, Te, Ti, Zn, and Zr, and the first layer is made of one of (i) the seed crystals formed by coalescing a plurality of grain crystals which adhere to the dielectric layer in an initial phase of the first layer formation, and (ii) the seed crystals formed by polycrystallization of an amorphous layer adhered to the dielectric layer in the initial phase of the first layer formation.
