MgO PROTECTION LAYER AND METHOD FOR MANUFACTURING PROTECTION LAYER FOR AC PDP CAPABLE OF AVOIDING CREATION OF HYDROXIDE ON SURFACE OF PDP

摘要

PURPOSE: An MgO protection layer and a method for manufacturing the protection layer are provided to improve a discharge property and lengthen the life span of PDP by preventing the creation of a hydroxide on the surface of PDP. CONSTITUTION: In an MgO protection layer for AC PDP, a covering layer constituted by one of aluminum oxide or zinc oxide is coated on the surface of the MgO protection layer. The thickness of the covering layer is 1 to 100nm. The covering layer is formed by using evaporation method.
