Cholesteric liquid crystal is an interesting and fascinating chiral supermolecular system, which has self-assemble helical alignment. In recent years, there are many excited research results about cholesteric liquid crystal, especially photo-tunable cholesteric liquid crystals. In this work, the development of photo-tunable cholesteric liquid crystals applications have been reviewed in these years in this paper. The application of photo-tunable cholesteric liquid crystal in special optics device will be a potential research fields.
