Abstract
A PDP includes a front panel including display electrode () formed on glass substrate (), dielectric layer () covering display electrode (), and protective layer () formed on dielectric layer (); and a rear panel opposing to the 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, wherein protective layer () is formed of a metal oxide made of magnesium oxide and calcium oxide and contains aluminum, and 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 in an X-ray diffraction analysis on a surface of protective layer ().
