Abstract
Provided is an antireflection film comprising a transparent support, at least one high refractive index layer having a refractive index higher by 0.05 or greater but not greater than 1.5 than that of the transparent support and a low refractive index layer having a refractive index lower by 0.05 or greater but not greater than 2.0 than that of the high refractive index layer, wherein the high refractive index layer contains matting agent particles having an average particle size of 0.3 μm or greater but not greater than 20 μm; and the film has a haze value of 10% or less. This antireflection film has a low reflectance, is clear, has a surface less tinged with white and has reduced color due to interference, so that it is suitably used for image display devices such cathode ray tube display device (CRT), plasma display panel (PDP) and liquid crystal display (LCD). The film is also used for a polarizing plate.
