Patent ID: 8120255

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; a rear panel disposed facing the front panel, such that a discharge space is formed between the front panel and the rear panel, the rear panel including an address electrode formed in a direction intersecting the display electrode, and including a barrier rib partitioning the discharge space; and a seal material providing a seal between the front panel and the rear panel at outer peripheries of the front panel and the rear panel, wherein the protective layer is formed by forming a base film on the dielectric layer and attaching a plurality of groups of aggregated particles to the base film, wherein each group of aggregated particles of the plurality of groups of aggregated particles is (i) in a lump form and (ii) comprises a plurality of metal oxide crystal particles piled up to form the lump form, and wherein each group of aggregated particles of the plurality of groups of aggregated particles is located discretely over a surface of a region inside the seal material.
