An anti-reflection film containing a high-refractive-index layer having a refractive index of 1.65 to 2.40 and a low-refractive-index layer having a refractive index of 1.20 to 1.55, wherein the high-refractive-index layer is formed by coating and hardening a coating solution composition that contains inorganic fine particles having an average particle size of 1 to 200 nm and being dispersed with a polymer having a crosslinkable group. A method of producing the anti-reflection film and an image display device provided with the anti-reflection film.
