Document Type and Number:
Japanese Patent JP4233379
Kind Code:
B2
Abstract:
A cholesteric liquid crystal film of the invention consist of a single layer, which is a cholesteric liquid crystal film, formed by applying a liquid crystal mixture containing a polymerizable mesogen compound (A) and a polymerizable chiral agent (B) to an alignment substrate, and applying ultraviolet irradiation to the mixture, wherein a cholesteric liquid crystal film has at least two independent selective reflection wavelength bands. The cholesteric liquid crystal film can be prepared by a simple and easy procedure.
