PROBLEM TO BE SOLVED: To provide a plasma display panel which can raise the purity of the inert gas within a discharge space, especially around a phosphor while maintaining its high production efficiency and high shape precision, and to provide a manufacturing method therefor. SOLUTION: Porous layers 6 are formed beneath phosphors 4 which are formed on a substrate 1. Since the porous layers 6 have a structure which is more porous than the ribs 2 or the phosphor layers 4, they absorb more moisture or carbon dioxide than the ribs 2 or the phosphors 4, and do not release impurity gas which they have absorbed once. As a result, the purity of the inert gas in the discharge space, especially in the space around phosphors is enhanced as compared with the purity of the inert gas in a conventional plasma display panel which does not have the porous layers 6.
