US 11,453,185 B2 · Micropattern layer based image film

Abstract

The present invention relates to a micropattern layer based image film and a method for manufacturing the same. The image film comprises: a sacrificial layer; a first micropattern layer formed on the sacrificial layer; a second micropattern layer formed on the first micropattern layer; a focal length layer formed on the second micropattern layer; and a micro-image pattern formed on the focal length layer, wherein the first micropattern layer includes a plurality of concave parts extending in one direction, and concave curved surfaces of the plurality of concave parts are formed adjacent to the sacrificial layer; the second micropattern layer includes a plurality of convex parts extending in one direction, and convex curved surfaces of the plurality of convex parts are formed adjacent to the focal length layer; and the first micropattern layer and the second micropattern layer are orthogonal to each other.
