Abstract:
The present invention relates to an antireflection film including a low refractive index layer and a hard coating layer, the low refractive index layer including: a binder resin containing a crosslinked polymer of a photopolymerizable compound and a polysilsesquioxane substituted with one or more reactive functional groups; and inorganic fine particles dispersed in the binder resin, wherein a 10-point average roughness (Rz) of the shape of irregularities on the surface of the low refractive index layer is 0.05 μm to 0.2 μm.
