  • Patent number: 7977883
    Abstract: Disclosed is a material for forming a protective layer, a protective layer employing the material and a PDP with the protective layer. Unlike conventional protective layers which employ MgO created in conditions of pressurized artificial gas, the instant protective layer uses MgO created by heating Mg and allowing it to oxidize naturally in air. The result is MgO with fewer defects that is more effective as a protective layer in many uses, such as in a PDP. The instant MgO also shows many specific spectral characteristics and contains impurities in amounts of less than about 2 ppm each. Also disclosed is a PDP which takes advantage of the advantages of the inventive protective layer.
