Disclosed is a plasma display panel that can realize high-definition and high-brightness display properties and, at the same time, has low power consumption. The plasma display panel comprises a front plate comprising display electrodes, a dielectric layer, and a protective layer. The display electrode is provided on a front glass substrate. The dielectric layer is provided so as to cover the display electrode. The protective layer is provided on the dielectric layer. A back plate comprises address electrodes in a direction that crosses the display electrodes, and partition walls that partition a discharge space. The front plate and the back plate are disposed opposite to each other so as to form the discharge space, and a discharge gas is filled into the discharge space. The protective layer has a substrate film provided on the dielectric layer. Agglomerated magnesium oxide crystal grains are deposited on the substrate film. Further, the substrate film contains a metal oxide comprising at least two oxides selected from magnesium oxide, calcium oxide, strontium oxide, and barium oxide. Regarding the metal oxide, the X-ray diffraction analysis of the surface of the substrate film shows a peak between a minimum diffraction angle and a maximum diffraction angle derived from a simple substance of the oxide constituting the metal oxide in a specific plane direction.
