Abstract
(EN)
The present invention relates to an optical laminate and a display device comprising the optical laminate, the optical laminate comprising: a substrate; and a hard coating layer formed on at least one surface of the substrate, the hard coating layer containing: a binder resin; and two or more kinds of inorganic particles having different average diameters, wherein a domain formed by enclosing two or more first inorganic particles in two or more second inorganic particles is formed in the hard coating layer, the first inorganic particle and the second inorganic particle being different components.
