A plasma display panel including a front panel including front glass substrate, a display electrode formed on the substrate, a dielectric layer covering the display electrode, a protective layer formed on the dielectric layer, and a rear panel facing the front panel so that a discharge space is formed. Further, the rear panel includes an address electrode formed in a direction intersecting the display electrode, and a barrier rib partitioning the discharge space. The protective layer includes a base film on the dielectric layer and aggregated particles of a plurality of aggregated metal oxide crystal particles attached to the base film, such that the aggregated metal oxide crystal particles are distributed over an entire surface. Specifically, the aggregated particles have a distribution of peak intensity values in a spectrum in a wavelength range of not less than 200 nm and not more than 300 nm of a cathode luminescence within 240% of a cumulative average value.
