| 简介 |
A material (X) for preparing a protective layer for a PDP, which reduces discharge delay time, improves temperature dependency, and has enhanced ion strength relative to other materials (9, 6); a method of preparing the same; a protective layer formed of the material; and a PDP including the protective layer. More particularly, a material for a protective layer that includes monocrystalline magnesium oxide doped with a rare earth element at an amount of 2.0×10-5 -1.0×10-2 parts by weight per 1 part by weight of magnesium oxide (MgO), a method of preparing the monocrystalline magnesium oxide by crystallizing it at about 2, 800°C, a protective layer formed of the same, and a PDP including the protective layer. |
