FIELD: physics.
SUBSTANCE: antireflection film has on its surface a moth eye structure which includes a plurality of convex portions, wherein the width between the peaks of adjacent convex portions does not exceed the wavelength of visible light. The moth eye structure includes a sticky structure formed by connecting top ends of the convex portions to each other and the diameter of the sticky structure is smaller than 0.3 mcm. The aspect ratio of each of the plurality of convex portions is less than 1.0, and the height of each of the plurality of convex portions is shorter than 200 nm.
EFFECT: reduced light scattering.
