Abstract
An antireflection film having a low reflectance and giving non-tinged reflected light with a low cost, which comprises: a transparent substrate; and a low-refractive layer having a lower refractive index than said transparent substrate, wherein the antireflection film has an average specular reflectance of 0.5% or less at an incidence angle of 5° in a wavelength region of from 450 to 650 nm, and, when CIE standard illuminant D65 in a wavelength region of from 380 to 780 nm is incident on the antireflection film at an incidence angle of 5°, the regular reflection light has a color having a* and b* values in a ranges specified by −7≦a*≦7 and −10*≦b*≦10 in the CIE 1976 L*a*b* color space.
