An effective way to achieve flexible color cholesteric LCD with single LC mixture and layer was proposed. The 1st-step for polymer wall formation and 2nd-step for color rendering were independently carried out without the interference of UV reaction

The bistable memory of a cholesteric liquid crystal often disappears owing to the unstable orientation of the focal conic state. We demonstrated the stabilization of the memory by controlling the boundary symmetry of a mono-layered cholesteric liquid

Here we report a method to achieve a full color cholesteric liquid crystal using single liquid crystal layer and single plastic substrate. Mixture of a photosensitive chiral dopant and a nematic host was encapsulated and coated onto a surface. By irr
