PROBLEM TO BE SOLVED: To provide an antireflection film having a low reflectance, superior antifouling properties and superior dust sticking preventing properties of the surface and to provide a polarizing plate using the film and an image display. SOLUTION: The antireflection film has at least one low refractive index layer on a transparent substrate and has <=2.5% average reflectance in the range of 450-650 nm. The surface layer of the antireflection film contains a fluoropolymer and has an F1s to C1s peak intensity ratio of 0.2-5.0 and an Si2p to F1s peak intensity ratio of 0.05-2.0 by X-ray photoelectron spectroscopy. The coefficient of dynamic friction of the surface of the antireflection film is <=0.25. A polarizing plate and an image display using this film are also presented. |
