Abstract

We have demonstrated multicolored reflections showing various whitish colors from a bichiral liquid crystal (LC) film. The bichiral LC film was fabricated by using left-handed and right-handed polymeric cholesteric liquid crystal (CLC) films with two different helical pitches and an isotropic polymer film in between. Color temperatures of the multiple reflections are controlled from ∼4000 K to ∼10000 K by changing linear polarization directions of normally incident and reflected lights. This characteristic can extend practical applications of CLCs to illuminant devices.
