For a PDP, a panel having favorable discharge properties such a high discharge efficiency and a short discharge delay, being chemically stable and capable of electric power saving, is desired. A plasma display panel comprising a front substrate and a rear substrate facing each other via a discharge space, discharge electrodes formed on at least one of the front substrate and the rear substrate, a dielectric layer covering the discharge electrodes, and a protective layer covering the dielectric layer, wherein the protective layer contains a Mayenite compound, and the secondary emission coefficients when Ne and Xe are used as excited ions at an accelerating voltage of 600 V, are respectively at least 0.05 at a secondary electron collector voltage at which secondary electrons can be sufficiently captured.
