Color cathode ray tube |
摘要 |
A large number of micropores are formed in a surface of a metal base body of a shadow mask provided to a color cathode ray tube and a surface film is formed such that the surface film impregnates these micropores and covers the metal base body. Due to such a constitution, it is possible to realize a color cathode ray tube having a press mask of a large radius of curvature which can reduce the thermal deformation such as doming.
