Abstract

Provided are a color display film, a method for manufacturing the same, and a display apparatus including the color display film. The color display film includes a base material layer, a high-refractive light diffusion layer including a light diffuser, a high-refractive resin layer, and a low-refractive resin layer on which an optical pattern is formed. The method for manufacturing a color display film includes forming a high-refractive light diffusion layer by coating a resin comprising a diffuser on one surface of a base material layer and hardening the resin, forming a high-refractive resin layer, in which optical patterns are formed, on one surface of the high-refractive light diffusion layer, and forming a low-refractive resin layer having optical patterns formed on one surface thereof by coating a low-refractive transparent resin on a surface of the high-refractive resin layer in which the optical patterns are formed and hardening the resin.
