CHOLESTERIC LIQUID CRYSTAL FILM, MANUFACTURING METHOD THEREFOR AND CIRCULARLY POLARIZED LIGHT REFLECTING FILM, TWO-WAVELENGTTTH REGION REFLECTION TYPE REFLECTING FILM

摘要

PROBLEM TO BE SOLVED: To provide a cholesteric liquid crystal film, which is obtained easily and having at least two independent selective reflection wavelength bands.

SOLUTION: The cholesteric liquid crystal film applies a liquid crystal mixture, containing a polymeric mesogen compound (A) and a polymeric chiral agent (B) on an orientation base material, and is obtained through irradiation of ultraviolet ray. The cholesteric liquid crystal film consists of a single layer and has at least two independent selective reflecting wavelength bands.
