Abstract:
A cathode ray tube comprising 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 said glass panel and said neck portion; and a high refractive index film 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 formed on an outer face of said glass panel, said high refractive index film being sandwiched between the outer face of said glass panel and said low refractive index film, wherein 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 said high refractive index film and said low refractive index film, and wherein the high refractive index film is conductive and includes at least one selected from the group consisting of electrically conductive metal oxide particles and metal particles.
