CHOLESTERIC LIQUID CRYSTALLINE FILM, METHOD FOR PRODUCIION THEREOF AND CIRCULARLY POLARIZED LIGHT REFLECTING FILM, TWO WAVELENGTH REGION REFLECTION TYPE REFLECTING FILM

摘要

A cholesteric liquid crystalline film, which is prepared by applying a liquid crystalline mixture containing a polymerizable mesogen compound (A) and a polymerizable chiral agent (B) on an alignment base material, followed by irradiation with an ultraviolet ray, characterized in that the cholestric film consists of one layer and has at least two independent wavelength regions of selective reflection. The cholesteric liquid crystalline film can be prepared by a simple and easy procedure.
