Abstract
There is disclosed an anti-reflection film comprising 5-65% by volume of inorganic fine particles having an average particle size of 1-200 nm and having a core/shell structure, and 35-95% by volume of a polymer, wherein a high-refractive-index layer having a refractive index of 1.65-2.40 and a low-refractive-index layer having a refractive index of 1.30-1.55 are laminated. There is also disclosed a polarizing plate and image display device utilizing the anti-reflection film. The anti-reflection film is suitable for mass production.
