摘要：

We have demonstrated polarization-independent multiple reflections covering overall visible region from a bichiral liquid crystal (LC) film with both chiral structures. The bichiral LC film was fabricated by an all-solution process using left-handed and right-handed polymeric cholesteric liquid crystal (CLC) films with a single pitch and an isotropic polymer film. The multiple reflections exceeding 50% reflectance were clearly observed at various polarizations of normally incident light. This characteristic can extend practical applications of CLCs to polarization-independent devices over broad-band regions.
