By irradiating polymer-cholesteric liquid crystal (CLC) composites with UV light, a polymer-separated double-layer structure is formed due to the inhomogeneous polymerization reactions of polymers in the upper and lower spaces. This double-layered cholesteric structure with two reflection bands makes it possible to broaden the reflection bandwidth in CLCs.
