An anti-reflection film comprises a high refractivenindex layer having a refractive index of 1.65-2.40, and anlow refractive index layer having a refractive index ofn1.20-1.55. Another anti-reflection film comprises only anlow refractive index layer having a refractive index ofn1.20-1.55. In the invention, the first improvement residesnin a high refractive index layer composed of inorganic finenparticles having a mean particle size of 1-200 nm in annamount of 5-65 vol.% and a crosslinked anionic polymer innan amount of 35 to 95 vol.%. The second improvementnresides in a low refractive index layer composed of inorganicnfine particles having a mean particle size of 0.5-200nnm in an amount of 50-95 wt.% and a polymer in an amount ofn5-50 wt.%, and two or more of those particles are piled upnto form micro voidsby the adjacent particles. |
