PCT No. PCT/JP85/00332 Sec. 371 Date Feb. 25, 1986 Sec. 102(e) Date Feb. 25, 1986 PCT Filed Jun. 13, 1985 PCT Pub. No. WO86/00467 PCT Pub. Date Jan. 16, 1986.The present invention relates to a cathode ray tube having a black matrix phosphor screen. In the cathode ray tube of the present invention, a film whose main component is oxide film is formed to cover a carbon layer of a black matrix formed on the inner surface of a face plate and a phosphor layer is formed on this film. Consequently, even if the carbon layer is thin, the carbon layer can be prevented from being burned and made white in the baking process so that a black matrix phosphor screen of high definition can be obtained. Thus, it is possible to provide a color cathode ray tube of high definition black matrix type type which is good in quality.
