Abstract

See full text

An antireflection film including a hard coating layer; and a low refractive index layer including a binder resin and hollow and solid-type inorganic nanoparticles dispersed in the binder resin. The solid-type inorganic nanoparticles are distributed more than the hollow inorganic nanoparticles near the interface between the hard coating layer and the low refractive index layer. The hollow inorganic nanoparticles have a thickness of a shell layer to a particle radius ratio of 0.3 or less. A method for manufacturing an antireflection film including: coating a resin composition including a photocurable compound or a (co)polymer thereof, a fluorine-containing compound containing a photoreactive functional group, a photoinitiator, and hollow and solid-type inorganic nanoparticles onto a hard coating layer, drying at a temperature of 35° C. to 100° C. and photocuring the same. The hollow inorganic nanoparticles have a ratio of the thickness of a shell layer to the particle radius of 0.3 or less.
