A plasma display panel has the front glass substrate and the back glass substrate which are placed opposite each other on either side of a discharge space, row electrode pairs formed on the front glass substrate, a dielectric layer covering the row electrode pairs, and a protective layer covering the dielectric layer. The protective layer has a structure of a lamination of a thin-film MgO layer by either vapor deposition or spattering and a MgO layer including magnesium oxide crystals causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by an electron beam. A ternary discharge gas including neon, xenon and helium fills the discharge space.
