METHOD FOR MANUFACTURING GAS DISCHARGE PANEL

摘要

PROBLEM TO BE SOLVED: To prevent moisture and carbon dioxide gas from infiltrating into a panel as impurities from a film adhering moisture and carbon dioxide gas, in a case of a protective film made of magnesium oxide in a gas discharge panel starting with a PDP. SOLUTION: With the gas discharge panel, impurity gas is removed by beam irradiation into a MgO film. Also, as to quality of the MgO film, one with high electron emission power and high-level anti-sputtering property can be obtained, which not only reduces manufacturing processes and allows effective use of energy but also a high-quality and long-life PDP is manufactured.
