ABSTRACT:
A cathode ray tube with a vacuum enclosure, including a glass panel having an inner face coated with a phosphor film to form a screen, a neck portion housing an electron gun, and a funnel portion connecting the glass panel and the neck portion. A high refractive index film made of electrically conductive metal oxide or metal (e.g., precious metal) particles and having a refractive index of 1.6 to 2.2, and a low refractive index film having a refractive index of 1.3 to 1.58, are formed on the outer face of the glass panel. The high refractive index film is sandwiched between the outer face of the glass panel and the low refractive index film and an average roughness of an outer surface of said low refractive index film is less than an average roughness of an unevenness of an interface between the high refractive index film and the low refractive index film.
