Patent ID: 8237363

Claim:
A plasma display panel, comprising: a front panel including a substrate, a display electrode formed on the substrate, a dielectric layer formed so as to cover the display electrode, and a protective layer formed on the dielectric layer; and a rear panel disposed facing the front panel so that a discharge space is formed, and including an address electrode formed in a direction intersecting the display electrode, and a barrier rib for partitioning the discharge space, wherein the protective layer includes a base film and a plurality of aggregated particles, the base film being formed on the dielectric layer and each of the plurality of aggregated particles being distributed uniformly over the entire surface of the base film, each aggregated particle including a plurality of crystal particles of metal oxide of a predetermined particle diameter and shape that are aggregated together by forces between the particles but not by adhesive bonding, each aggregated particle comprises a plurality of the crystal particles piled up on each other to form an aggregated lumped formation and the base film is made of MgO containing Al.
