Abstract:
1. A complex optical film comprising: a first substrate; a light shielding layer formed on a bottom surface of the first substrate; an optical pattern layer formed on a top surface of the first substrate and including concavo-convex portions; a second substrate disposed on the first substrate; and a first adhesive layer disposed under the second substrate, wherein the light shielding layer includes a binder and organic particles and inorganic particles dispersed in the binder, the convex portions of the optical pattern layer at least partially penetrate into the first adhesive layer to be combined with the first adhesive layer, and a low-refraction area having a lower refractive index than the optical pattern layer and the first adhesive layer is defined between the first adhesive layer and the optical pattern layer, wherein surface roughness of the optical pattern layer is larger than that of the light shielding layer.
