Cathode ray tube and method for manufacturing thereof
The present invention discloses a method for manufacturing a cathode ray tube capable of forming on an inner surface side of a panel a conductive reflective film and a heat absorbing film, both being excellent in the characteristics and the film qualities thereof, which comprises a first step for forming on a fluorescent film preliminarily formed on the inner surface of a panel a conductive reflective film by depositing aluminum by the vacuum evaporation process; a second step for forming a diffusion preventive film made of aluminum oxide on the surface of the conductive reflective film; and a third step for forming a heat absorbing film on the diffusion preventive film by depositing chromium by the vacuum evaporation process.
