An anti-reflection film having superior anti-reflection properties and which is suited for practical application is to be manufactured easily and simply with high productivity and a reduced manufacturing cost. To this end, there are sequentially formed by layering, an adhesive layer 4, a first optical thin film 5, containing one or more of titanium nitride, hafnium nitride and zirconium nitride, and a second optical thin film 6 having a refractive index of 1.35 to 1.7. The adhesive layer 4 is represented by the chemical formula of SiOx, where x<2. If the first optical thin film 5 mainly contains titanium nitride, the first optical thin film 5 preferably is electrically conductive. The second optical thin film 6 is preferably formed of SiO2. A cathode ray tube may be provided by arranging the resin substrate 3, carrying the respective layers, on a face plate side of the display portion, with the remaining configuration of the anti-reflection film being the same as above.
A cathode ray tube wherein, on a face plate surface side of a display portion, comprising an anti-reflection film having a three-layered structure consisting of an adhesive layer consisting essentially of SiOx where x<2, the adhesive layer being formed on a major surface of a resin substrate, a first optical thin film consisting essentially of titanium nitride doped with a metal, said first optical film formed on said adhesive layer, and a second optical thin film with a refractive index of 1.35 to 1.7 formed on said first optical thin film, said anti-reflection film being arranged facing said resin substrate.
An anti-reflection film having a three-layered structure consisting of an adhesive layer consisting essentially of SiOx where x<2 wherein the adhesive layer is formed on a major surface of a resin substrate;
