Liquid crystal polymerized films using alignment film and polymerizable liquid crystal compostion

Abstract

Liquid crystal polymerization films, prepared by applying a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound represented by formula (2) on an alignment film prepared by calcinating a composition containing a polymer represented by a repeating unit of formula (1), and subsequently polymerizing the polymerizable liquid crystal composition. In formula (1), R1 is independently a tetravalent group, R2 is independently a divalent functional group and R3 is independently a hydrogen atom or a monovalent functional group. PG1-Sp1-R4-Sp2-PG2  (2) In formula (2), R4 represents a divalent group formed by combining five or more and nine or less of alicycles and/or aromatic rings, SP1 and SP2 represent a spacer group, and PG1 and PG2 represents an alkyl group, an alkoxyl group, a cyano group, fluorine or a polymerizable functional group, in which either group is the polymerizable functional group.
