Abstract
Official abstract text for this publication.
A method for producing a light diffusion film having first and second louver structure regions includes the following steps (a) to (d): (a) preparing a composition for light diffusion film; (b) applying the composition for light diffusion film, and forming a coating layer; (c) performing first active energy ray irradiation, and forming a first louver structure region in the lower part of the coating layer, while leaving a louver structure-unformed region in the upper part of the coating layer; and (d) performing second active energy ray irradiation, and forming a second louver structure region in the louver structure-unformed region.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a light diffusion film having a first louver structure region and a second louver structure region, wherein comprise plural plate-shaped regions having different refractive indices alternately arranged in parallel along any one direction along the film plane, and the light diffusion film comprises an overlapping structure region in which the upper end of the first louver structure region extends into the lower end of the second lo…
