Abstract

Provided are structural coloration, a method for manufacturing a structural coloration substrate, and a security verification system using the structural coloration substrate manufactured thereby. The method for manufacturing a structural coloration substrate comprises: a step for disposing an upper substrate on a base substrate; a step for using quantum dots to form a first pattern, which displays a first color, on the upper substrate; and a step for laminating at least one structural coloration layer on the upper substrate on which the first pattern has been formed. The first color of the first pattern is changed and displayed due to the lamination of the structural coloration layer.

Description

technical field [0001] The present disclosure relates to a structurally colored substrate, a method for manufacturing a structurally colored substrate, and a security verification system using a structurally colored substrate manufactured by the method, and more particularly, the present disclosure relates to providing a Structurally colored structurally colored substrates for structurally colored reflected light of various colors, a method for manufacturing the structurally colored substrates, and a security authentication system using the structurally colored substrates manufactured by the method. Here, the structural coloring substrate is a complex structural coloring substrate to be encrypted, and thus the security verification system can confirm whether the currency or the expensive product is genuine. Background technique [0002] When light is incident into the film, light reflected from the surface of the film and light reflected from the film after passing through t...
