ANTI-REFLECTION FILM AND PRODUCTION METHOD THEREFOR

摘要

An anti-reflection film according to the present invention includes: a substrate; and a medium-refractive index layer, a high-refractive index layer, and a low-refractive index layer in the stated order from a substrate side. When optical design of a reflection characteristic of the anti-reflection film is performed with a complex plane of a reflectance amplitude diagram at a wavelength of 580 nm, refractive indices and/or thicknesses of the substrate, the medium-refractive index layer, the high-refractive index layer, and the low-refractive index layer are designed in such a manner that a line AB connecting a starting point A and an ending point B of a lamination locus of the high-refractive index layer intersects a real axis of the reflectance amplitude diagram.
