WIDE-BAND CHOLESTERIC LIQUID CRYSTAL FILM, ITS MANUFACTURING METHOD, CIRCULAR POLARIZING PLATE, LINEAR POLARIZER, ILLUMINATION APPARATUS AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a wide-band choresteric liquid crystal film which is made thin, has a wide reflection band and can be manufactured in a smaller number of manufacturing processes.;SOLUTION: The wide-band choresteric liquid crystal film is obtained by applying a liquid crystal mixture containing a polymerizable mesogene compound (a), a polymerizable chiral agent (b) and a photo-isomerization material (c) on a base material and subjecting the coating to UV polymerization, and it is characterised by having ≥200 nm reflection band width.;COPYRIGHT: (C)2004,JPO&NCIPI
