Abstract:
An optical film manufacturing method includes forming a master in which a shape corresponding to a plurality of micro-lens patterns is engraved, forming a low refractive index pattern layer in which the plurality of micro-lens patterns are formed, by using the master, forming a high refractive index material layer that has a higher refractive index than a refractive index of the low refractive index pattern layer, and imprinting the low refractive index pattern layer on the high refractive index material layer to form a high refractive index pattern layer, on a first surface of a substrate.
Abstract:
Provided is a color improving film comprising a base layer, a high refractive light diffusion layer including an organic light diffuser on the base layer, a high refractive resin layer on the high refractive light diffusion layer, and a low refractive resin layer in which a lenticular lens pattern is formed on the high refractive resin layer, wherein the organic light diffuser comprises particles coated with a black pigment and non-coated particles, and wherein the lenticular lens pattern is formed on a surface of the low refractive resin layer facing the high refractive resin layer. According to the color improving film, a change in color sensitivity according to an angle of view is small, an external light reflectivity is low, and a light transmittivity and a light diffusibility are substantially improved. Also, the method of preparing the color improving film has excellent processiblity and economic efficiency.

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.
