Abstract
The present invention relates to an antireflection film being capable of realizing high scratch resistance and antifouling property while simultaneously having low reflectivity and high light transmittance, and further being capable of enhancing screen sharpness of a display device.
Claims15
An antireflection film comprising:
- a hard coating layer or an antiglare layer;
- and
- a low refractive index layer formed on one side of the hard coating layer or the antiglare layer and including a binder resin, and hollow silica nanoparticles, metal oxide nanoparticles, and inorganic nanoparticles dispersed in the binder resin,
- wherein a first region containing the hollow silica nanoparticles, a second region containing the metal oxide nanoparticles, and a third region containing the inorganic nanoparticles are present in the low reflective index layer,
- and wherein the low refractive index layer has at least one diffraction peak in a range in which a value of 2θ, twice the angle of incidence of an incident X-ray, is from 50° to 60° in a grazing-incidence X-ray diffraction (GID) spectrum.
