Abstract:
1. A plasma display panel comprising: a first substrate including; a second substrate disposed facing the first substrate, such that a discharge space is formed between the first substrate and the second substrate, wherein the discharge space is filled with a discharge gas, wherein the second substrate includes an address electrode formed along a direction intersecting the display electrode, wherein the second substrate includes a barrier rib partitioning the discharge space, wherein the protective layer is formed of a metal oxide comprised of magnesium oxide (MgO) and calcium oxide (CaO) having a structure such that an X-ray diffraction analysis on a surface of the protective layer indicates that the metal oxide has a peak between a diffraction angle where a peak of the MgO occurs and a diffraction angle where a peak of the CaO occurs along an identical orientation of the peak of the MgO, wherein a density of calcium of the metal oxide is within a range between 5 atomic % and 25 atomic % inclusive, and wherein the metal oxide has a peak indicating a crystal orientation of a (111) plane.
