ABSTRACT:
A cathode ray tube in which a shadow mask assembly constituted by a shadow mask and a mask frame is positioned to face a phosphor screen formed on the inner face of a panel at a predetermined distance. The shadow mask and/or the mask frame is plated with a nickel film 0.5 to 3.0 microns thick and is subsequently blackened, thereby preventing a black oxide film from peeling off the shadow mask assembly.
