Abstract
A plasma display panel (PDP), which is capable of performing a display with a high brightness and having a low power consumption, includes a front panel having display electrodes formed, a dielectric layer covering the display electrodes, and a protective layer formed on the dielectric layer. Further, the PDP includes rear panel having address electrodes formed along a direction intersecting the display electrodes, and barrier ribs. The front and rear panels form, therebetween, a discharge space portioned by the barrier ribs and filled with discharge gas. A protective layer is formed of a metal oxide of MgO and CaO, 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 MgO occurs and a diffraction angle where a peak of CaO occurs along an identical orientation of the MgO peak.
