Abstract:
An antireflection film includes: a substrate; and an antireflection layer formed with a composition containing metal oxide particles having surface hydroxyl groups as particles for forming a moth eye structure, and two compounds having (meth)acryloyl groups, where the antireflection layer contains a binder resin including at least one of a structure derived from the two (meth)acryloyl groups, and the moth eye structure has an irregular shape formed with the metal oxide particles on a surface on a side opposite to an interface on the substrate side, and in the irregular shape of the antireflection layer, B/A is a ratio between a distance A between peaks of adjacent convex portions and a distance B between a center between peaks of the adjacent convex portions and a concave portion is 0.5 or greater.
