Abstract
The present invention relates to an anti-reflective film including: a hard coating layer; and a low refractive layer that is formed on one side of the hard coating layer, and includes porous inorganic nanoparticles with a diameter of 5 nm to 70 nm including micropores with a diameter of 0.5 nm to 10 nm, and a binder resin, and a method for preparing an anti-reflective film.
Claims17
An anti-reflective film comprising:
- a hard coating layer;
- and
- a low refractive layer that is formed on one side of the hard coating layer, and comprising porous inorganic nanoparticles with a diameter of 5 nm to 70 nm comprising micropores with a diameter of 0.5 nm to 4.5 nm, and a binder resin,
- wherein the anti-reflective film exhibits mean reflectance of 0.40% or less in the visible light wavelength region of 380 nm to 780 nm, and
- wherein the porous inorganic nanoparticles have a BET surface area of 917.5 m2/g to 2000 m2/g and the diameter of the micropores are measured based on a Barret-Joyner-Halenda (BJH) analysis.
