Method of manufacturing a cathode ray tube

摘要

The present invention discloses a method for manufacturing a cathode ray tube (10) capable of forming on an inner surface side of a panel (11) a conductive reflective film (15) and a heat absorbing film (16), both being excellent in the characteristics and the film qualities thereof, which comprises a first step for forming on a fluorescent film (14) preliminarily formed on the inner surface of a panel a conductive reflective film (15) by depositing aluminum by the vacuum evaporation process; a second step for forming a diffusion preventive film (31) made of aluminum oxide on the surface of the conductive reflective film (15); and a third step for forming a heat absorbing film (16) on the diffusion preventive film by depositing chromium by the vacuum evaporation process.
