Abstract
Provided are an anti-reflective film, a polarizing plate comprising same, and an optical display device comprising same, wherein in the anti-reflective film, a base layer, a high-refractive layer, and a low-refractive layer are sequentially stacked, the low-refractive layer comprising inorganic hollow particles having an average particle diameter of about 70 nm to about 150 nm, the low-refractive layer comprising a single layer arrangement of the inorganic hollow particles.
