Abstract
An antireflection film including: a plastic substrate; and an antireflection layer, where the antireflection layer includes a metal oxide particle and a binder resin, the antireflection layer has a moth eye structure including an uneven shape formed by the metal oxide particle, a total light transmittance of the antireflection film where light is incident from a side of the antireflection layer opposite the plastic substrate is 88% or more, and where transmittances of light at wavelengths of 480 nm and 580 nm of the antireflection film where the light is incident from a side of the antireflection layer opposite the plastic substrate are respectively T480 and T580, T580−T480≤3.5% is satisfied, and a method of manufacturing the antireflection film, and an antireflection product, a polarizing plate, an image display device, a module, and a liquid crystal display device with a touch panel, containing the antireflection film.
