Abstract
Disclosed is an antireflection film used to be stuck on the surface of a glass panel of a CRT, which can be inexpensively manufactured at a high productivity while satisfying all of requirements regarding its adhesive strength, reflectance characteristic, electric resistance and total light transmittance. The antireflection film is formed by stacking silicon oxide films and indium tin oxide films on a base film in multilevels, wherein the thickness of the uppermost silicon oxide film of the antireflection film is thicker than the indium tin oxide film directly under the uppermost silicon oxide film, and the lowermost silicon oxide film, positioned at the interface with the base film, of the antireflection film is a SiO,film where the value x is in a range of 0.5 to 1.9.
