ABSTRACT:
An antireflection film is formed of an organic film, and a hard-coating layer, a high refractive index layer and a low refractive index layer laminated in this order on the organic film. The high refractive index layer is formed of metal oxide particles of ITO with electrical conductivity and TiO2with high refractive index, and synthetic resin. A volume percentage of the TiO2particles to a total volume of the TiO2and ITO particles in the high refractive index layer is 1 to 60%, and a volume percentage of the metal oxide particles to a total volume of the metal oxide particles and the synthetic resin is 20% or more.
