A plasma display panel is provided with a front plate and a rear plate disposed to oppose the front plate. The front plate includes a display electrode, a dielectric layer covering the display electrode, and a protective layer covering the dielectric layer. The protective layer includes a base layer and a metal oxide formed on the base layer. The metal oxide is resulted from grinding a metal oxide coarse particle. The metal oxide and the metal oxide coarse particle have peaks of photoluminescence in a wavelength range between 200 nm and 300 nm. The peak of the metal oxide has an intensity that is 60% or more and less than 100% of that of the peak of the metal oxide coarse particle. |
