Abstract
A high definition plasma display panel which can display a video of a higher brightness and yet can be driven at a low power consumption is realized. To this end, a plasma display panel includes front panel including display electrode formed on glass substrate, dielectric layercovering display electrode, and protective layer formed on dielectric layer; and a rear panel opposing to front panel to form a discharge space filled with discharge gas, and including an address electrode formed along a direction intersecting with display electrode, and a barrier rib partitioning the discharge space. Protective layer is formed of a metal oxide made of magnesium oxide and calcium oxide and contains silicon. In an X-ray diffraction analysis on a surface of protective layer, a diffraction angle where a peak of the metal oxide occurs exists between a diffraction angle where a peak of the magnesium oxide occurs and a diffraction angle where a peak of the calcium oxide occurs.
