To provide a method of manufacturing PDP for preventing large-small particles of protective layer forming raw materials from mixing at the time of application and drying.
In this method of manufacturing a plasma display panel, a protective layer is formed on a front plate through processes including: (i) a process in which a first protective layer raw material containing first MgO particles and a first solvent and a second protective layer raw material containing second MgO particles and a second solvent are prepared; (ii) a process in which the first protective layer raw material and the second protective layer raw material are simultaneously applied to a dielectric layer formed on a base plate of a front plate and thereby a protective layer raw material layer having a two-layer structure of the first protective layer material layer and the second protective layer material layer is formed; and (iii) the protective layer raw material layer having a two-layer structure is dried; the particle size of the first MgO particles being smaller than that of the second MgO particles in the first and second protective layer raw materials prepared in the process (i), and the surface of the dielectric layer facing downward in the vertical direction when the first and second protective layer raw materials are simultaneously applied to that surface in the process (ii).
