Abstract
【解決手段】本発明は、第1ドーピング物質のBeO、CaOなどのようなアルカリ土金属酸化物と、第2のドーピング物質のSc2O3、Sb2O3、Er2O3、Mo2O3又はAl2O3などのような酸化物とが同時にドーピングされたMgOパレットを蒸着源として用いて真空蒸着する方法により保護膜を形成する構成からなっている。本発明によれば、PDPの放電効率を画期的に向上させることが可能であり、且つ、放電遅延を減少させることでシングルスキャンPDPの適用が可能となり、電子部品点数の減少によるPDP原価コストを削減させることができることから、PDPの特性を向上させ、モージュルの原価を減少させることができるという利点がある。
