PROBLEM TO BE SOLVED: To attain a plasma display panel having a high-definition and high-luminance display performance and low power consumption. SOLUTION: In the method of manufacturing a plasma display panel, the protection film of the front plate is formed by forming a base film on a dielectric layer and adhering an aggregated particle formed by aggregating a plurality of crystal particles of a magnesium oxide onto the base film. The base film is made of a metal oxide consisting of at least two or more oxides selected from a magnesium oxide, a calcium oxide, a strontium oxide, and a barium oxide. A peak of the metal oxide is present 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 orientation plane in X-ray diffraction analysis of the base film surface. The step of forming the protection layer has the base film forming step, the oxidizing step and the crystal particle forming step. COPYRIGHT: (C)2011,JPO&INPIT
