ONE BODY TYPE OPTICAL FILM, METHOD FOR MANUFACTURING DIFFUSION LAYER, AND METHOD FOR MANUFACTURING ONE BODY TYPE OPTICAL FILM USING METHOD FOR MANUFACTURING DIFFUSION LAYER

摘要

PURPOSE: An integrated optical film, a diffusion layer manufacturing method, and an integrated optical film manufacturing method using the same are provided to prevent dislocation between a diffusion layer and a refractive layer unless excessive external force bigger than tolerance is applied even if the period of use is lengthened. CONSTITUTION: A first diffusion layer is manufactured by using a first mold having a first pattern corresponding to a first concave diffusion part (S10). The first diffusion layer is laminated on the upper or lower surface of a base layer, and a refractive layer or an optical transmission layer is laminated on the first diffusion layer (S20). The first diffusion layer is fully hardened to be integrated with the refractive layer or the optical transmission layer, and then integrated with the base layer (S30). [Reference numerals] (S10) Manufacture diffusion layer of pseudo hardened state; (S20) Laminate diffusion layer of pseudo hardened state to be neighborly located with a layer to be integrated with diffusion layer; (S30) Fully harden laminated diffusion layer of pseudo hardened state to produce integrated optical film
