ABSTRACT:
An anti-reflection film includes a transparent support and a low refractive index layer. A refractive index of the low refractive index layer is lower than a refractive index of the transparent support. The low refractive index layer contains micro voids in an amount of 3 to 50 volume % of the low refractive index layer. The anti-reflection film further has an overcoating layer provided on the low refractive index layer. The overcoating layer contains a fluorine compound. The fluorine compound is not present in the micro voids, or an amount of the fluorine compound present in the micro voids is less than 70 volume % of the micro voids.
