Abstract
Provided are a color improving film and a method of manufacturing the color improving film. The color improving film includes a base layer, a high refractive light diffusion layer comprising a light diffuser, a high refractive resin layer, and a low refractive resin layer in which a lenticular lens pattern is formed, wherein the base layer, the high refractive light diffusion layer, the high refractive resin layer, and the low refractive resin layer are stacked, wherein the lenticular lens pattern is formed on a surface of the low refractive resin layer facing the high refractive resin layer, and a unit lenticular lens of the lenticular lens pattern is an oval lenticular lens, wherein the color improving film satisfies 0.10<Δn<0.20, Δn=n1−n2, where n1 denotes a refractive index of the high refractive resin layer, and n2 denotes a refractive index of the low refractive resin layer.
