摘要：
A method for manufacturing a color CRT includes the step of coating a shadow mask of the color CRT in black. It further includes the step of forming an electron beam reflecting film by depositing tungsten oxide with a large electron beam reflection coefficient on the side of an electron beam irradiated surface of the shadow mask coated in black.
