Abstract: Described herein is an anti-reflective film including: a hard coating layer; and a low-refractive layer containing a binder resin and hollow inorganic nanoparticles and solid inorganic nanoparticles dispersed in the binder resin. The hollow and solid inorganic particles are dispersed in the low-refractive layer such that the amount of the solid inorganic nanoparticles positioned close to an interface between the hard coating layer and the low-refractive layer is larger than that of the hollow inorganic nanoparticles. Also described is a manufacturing method of the anti-reflective film including: applying a resin composition containing a photopolymerizable compound or a (co)polymer thereof, a fluorine-containing compound including a photoreactive functional group, a photoinitiator, hollow inorganic nanoparticles, and solid inorganic nanoparticles on a hard coating layer, and drying the applied resin composition at a temperature of 35° C. to 100° C.; and photocuring the dried resin composition.

Abstract: The present invention relates to a low refractive layer and an anti-reflective film comprising the same. The low refractive layer can exhibit excellent optical properties such as a low reflectance and a high light transmittance, and excellent mechanical properties such as high wear resistance and scratch resistance at the same time. In particular, due to the excellent alkali resistance, the low refractive layer can maintain excellent physical properties even after alkali treatment. Therefore, when introducing a low refractive layer to the display device, it is expected that the production process can be simplified and further the production rate and the productivity can significantly increase.
