Abstract
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 , a first optical thin film , containing one or more of titanium nitride, hafnium nitride and zirconium nitride, and a second optical thin film having a refractive index of 1.35 to 1.7. The adhesive layer is represented by the chemical formula of SiO , where x<2. If the first optical thin film mainly contains titanium nitride, the first optical thin film preferably is electrically conductive. The second optical thin film is preferably formed of SiO . A cathode ray tube may be provided by arranging the resin substrate , 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.
