Patent ID: 8164262

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 being disposed facing the front panel so that a discharge space is formed, the rear panel including an address electrode formed in a direction intersecting the display electrode, a plurality of longitudinal barrier ribs arranged in parallel to the address electrode, and a plurality of lateral barrier ribs combined with the longitudinal barrier ribs to form mesh-shaped barrier ribs, wherein the protective layer is formed by forming a base film on the dielectric layer and attaching a plurality of aggregated particles obtained by aggregating a plurality of crystal particles made of a metal oxide to the base film so as to be discretely distributed over a surface of the base film, and wherein the longitudinal barrier ribs and the lateral barrier ribs are formed so that a height of the lateral barrier ribs is lower than a height of the longitudinal barrier ribs.
