Abstract
Due to their periodic helical structure, cholesteric liquid crystals (CLC) have a unique ability to selectively reflect visible light. CLC films reflecting a broad wavelength band were made by inducing a pitch gradient in CLC through a diffusion of small molecules and through a thermal diffusion between two CLC oligomer films with different pitch gradients.
