Abstract
In a structural coloration substrate, a method for manufacturing the structural coloration substrate, and a security verification system using the structural coloration substrate manufactured by the method, the method includes forming a first pattern displaying a first color on a base substrate, using a quantum dot, and stacking at least one structural coloration layer on the base substrate on which the first pattern is formed. The first color of the first pattern is changed and displayed, as the at least one structural coloration layer is stacked.
