  • Publication number: 20110133639
    Abstract: A plasma display panel (PDP) featuring the display performance of high definition display and a high brightness, and yet, a lower power consumption is disclosed. A front panel of this PDP includes display electrodes formed on a front glass substrate, a dielectric layer covering the display electrodes, and a protective layer formed on the dielectric layer. A rear panel of this PDP includes address electrodes formed along a direction intersecting with the display electrodes, and barrier ribs. The front panel and the rear panel confront each other to form a discharge space which is filled with discharge gas and is portioned by the barrier ribs. The protective layer is formed of a metal oxide made of MgO and CaO. X-ray diffraction analysis on the surface of the protective layer finds 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.
