P‐131: Multi‐Color Cholesteric Liquid Crystal Film by Fixing Helical Pitch with Reactive Mesogen

Abstract We propose a multi‐color cholesteric liquid crystal (CLC) film in a single‐layered configuration with reactive mesogen (RM). The cholesteric pitches are controlled by temperature and memorized by photo‐polymerization of the KM. Using the multi‐pitch stabilization in a single layer, multicolor CLC display was obtained without any additional components.
