Claims23
A plasma display panel (PDP) protective layer comprising a material selected from the group consisting of Ba2X2O5, Ba3X4O9, and Ba4X2O7, wherein X is selected from the group consisting of Sc, Y, Gd, La, Er, Ho, Nd, Sm, and Ce.
A method of manufacturing a plasma display panel (PDP) protective layer, the method comprising:
- uniformly mixing BaO and X2O3, in ratios of 2:1, 3:2, or 4:1, with a solvent;
- heat-treating the mixture;
- and
- forming a deposition layer using the heat-treated material,
- wherein X is selected from the group consisting of Sc, Y, Gd, La, Er, Ho, Nd, Sm, and Ce.
A plasma display panel (PDP), comprising:
- a front substrate;
- a rear substrate disposed opposite to the front substrate;
- a protective layer disposed on a rear surface of the front substrate, the protective layer comprising a single phase, ternary barium oxide.
