Patent ID: 8198813

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 discharge space is formed, said rear panel 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 on the dielectric layer, the base film being made of magnesium oxide, and a plurality of aggregated particles on the base film, each aggregated particle being a plurality of piled up crystal grains of magnesium oxide, wherein the aggregated particles are distributed over an entire surface of the base film, and wherein the aggregated particles are attached so that the number of aggregated particles per 10000 μm 2 is not less than 45 and not more than 350.
