Abstract
Disclosed is a multilayer film comprising a substrate bearing an aligned liquid crystal layer wherein the aligned liquid crystal layer contains an azolium salt represented by formula (I): wherein the subscripts represent the ring positions and each X is independently N or C—R; each Z is independently N, N—R, C—(R)(R), O, S, SO, SO, C═O, C═S, or C═NR; each R group is independently hydrogen or a substituent; and Y is a charge balancing anion, which may be a separate moiety or part of an X, Z, or R; provided two or more X, Z and R groups may form a ring; provided the salt may be part of an oligomer or polymer. Such a film provides a predetermined increase in pre-tilt angle for use in liquid crystal devices.
