Abstract:
The method of making an optical body includes coating a mixture that includes a plurality of cholesteric liquid crystal compositions, and a solvent on a substrate. Each cholesteric liquid crystal composition is different. A plurality of layers is formed on the substrate. Each layer includes a majority of one of the cholesteric liquid crystal compositions.
