Abstract
A polymer film without cholesteric liquid crystal (LC) is characterized in that the polymer film has photonic crystal structure. The polymer film is an innovative product in the feature of having photonic crystal structure without containing cholesteric LC. In addition, the polymer film can further contain fluid which is filled in the film body of the polymer film. By filling any of various fluids in the film body, the light of different wavelengths can be reflected by the polymer film based on Bragg reflection, so that the applications of the polymer film can be broadened. Especially when the fluid is anisotropic liquid, the polymer film can be applied to electro-controlled reflective display modules. In addition, stacking the imprinted polymer films manufactured from left-handed and right-handed cholesteric liquid crystals can improve the brightness of reflected light.
