In-Plane Random Alignment of Liquid crystals on Hydroxypropyl Cellulose Film

Abstract

In-plane alignment of liquid crystal molecule, 4-n-octyl-4'-cyanobiphenyl (8CB), on a hydoroxypropyl cellulose was investigated from a microscope observation and an optical instrument measurement. Clear bright patterns were always observed with crossed polarizers The director directions of outgoing side of a nematic cell were determined from the combination of the polarization of incident and scattered light which was obtained by detecting the maximum transmitted intensity.
