Abstract
The present invention is to provide a process for manufacturing a fluorescent film wherein the order of coating the fluorescent films of a color Braun tube and the thickness of the film are adjusted to reduce the amount of red fluorescent material employed for red fluorescent film without deteriorating the quality of the red fluorescent film, thereby lowering the cost for manufacturing. The process first forms the red fluorescent film on the panel of a color Braun tube and then forms the blue and green fluorescent films subsequently thereafter.
