FIELD: physics.
SUBSTANCE: antireflection film has, on its surface, a moth-eye structure including a plurality of convex portions such that a width between vertices of adjacent convex portions is not greater than a wavelength of visible light, wherein the moth-eye structure includes a sticking structure formed when tip end portions of the convex portions are joined to each other. The diameter of the sticking structure is greater than or equal to 0.3 mcm and density of the number of sticking structures per unit area of the plane of the antireflection film is lower than 2.1 units/mcm2.
EFFECT: reduced light scattering.
