Abstract:
A cathode ray tube includes a film which is formed on an outer surface of a panel portion. The film is comprised of a first particles which become transparent due to the oxidation and a second particles which are chemically and physically stable and have the light absorbing ability and the conductivity. A number of the transparent first particles is gradually increased toward a peripheral portion from the center portion of the panel portion.
