The invention provides an antiglare coating layer composition capable of overcoming the problem of conventional techniques and providing further functionality in the antiglare thin film. More specifically, the invention provides an antiglare coating layer composition for simply producing the antiglare thin film. The antiglare thin film can be applied to a display device such as a liquid crystal television. Under light beam, it does not only improve phenomenon such as mapping and bleaching, but also provides excellent contrast performance, especially for black thick (as transparent black with powerful luster), and it has excellent anti-fingerprint property. The composition of the invention is for forming the antiglare layer on the transparent substrate and comprises a first component and a second component. The first component is acrylic copolymer containing unsaturated double bonds. The second component contains polyfunctional unsaturated double bonds, containing monomers having unsaturated double bonds of two-functional groups or more. The composition further comprises a carbamate (methyl) acrylate ester (A) containing polyether skeleton as a third component; and/or a (methyl) acrylate ester (B) having cyclic structure and containing at least one reactive unsaturated double bond, in which the refractive index is above 1.52, as a fourth component. Further, after coating the composition on the transparent substrate, the first component separates from the second component based upon the physical property difference between the first component and the second component so as to form the antiglare layer having random irregularities on the surface.
