    Abstract: A cathode ray tube (CRT) includes a base film and a reflection preventing multiple layer film on one surface of the base film, an adhesive layer on the other surface of the base film, including an adhesive polymer resin, and at least one organic or inorganic pigment or dye having a main light absorption region including a wavelength of 490 or 575 nm. The reflection preventing multiple layer film has, alternately stacked, a high refractive layer and a low refractive layer. The functional film has a wide application range, e.g., from a dark tint panel having low light transmission to a clear panel having a light transmission of 80% or more. A CRT having such a functional film has improved contrast characteristics and provides a high quality of picture and good color. The film is attached to the external surface of the glass panel at room temperature so that physical and other characteristics of the CRT are not adversely affected by sintering at a high temperature.
