Abstract
Disclosed herein is an anti-reflective film comprising: a hard coating layer; and a low-refractive layer containing a binder resin and hollow inorganic nanoparticles and solid inorganic nanoparticles which are dispersed in the binder resin, wherein a ratio of an average particle diameter of the solid inorganic nanoparticles to an average particle diameter of the hollow inorganic nanoparticles is 0.26 to 0.55, and wherein at least 70 vol % of the entire solid inorganic nanoparticles are present within a distance corresponding to 50% of an entire thickness of the low-refractive layer from the interface between the hard coating layer and the low-refractive layer, and an anti-reflective film comprising: a hard coating layer containing a binder resin containing a photocurable resin, and organic or inorganic fine particles dispersed in the binder resin; and a low-refractive layer containing a binder resin and hollow inorganic nanoparticles and solid inorganic nanoparticles which are dispersed in the binder resin, wherein a ratio of an average particle diameter of the solid inorganic nanoparticles to an average particle diameter of the hollow inorganic nanoparticles is 0.15 to 0.55, and w…
