Light diffusing film, manufacturing method thereof, and display apparatus comprising same

Abstract

A method of manufacturing a light diffusion film includes preparing a cylindrical drum having protrusions extending in a length direction on an outer circumferential surface; moving a base film having a defined width in a first direction; rubbing the cylindrical drum on the base film to form a plurality of grooves extending in a second direction perpendicular to the first direction; supplying, to the moving base film, a mixture having anisotropic light diffusion particles and a resin to fill the plurality of grooves; and curing the resin of the mixture in the plurality of grooves. The light diffusion film includes a base film with parallel grooves filled with resin containing anisotropic light diffusion particles, wherein the length of the particles is greater than the width of the grooves.
