Uniform Electrooptic Effects of Thick Freely Suspended Ferroelectric Liquid Crystal Film

Abstract

Ferroelectric Liquid Crystal (FLC) has fluidity and layered structure, so that freely suspended (FS) films of it can be made in air successfully. In the freely suspended ferroelectric liquid crystal (FSFLC) films, a molecular reorientation is induced by application of an electric field parallel to the film. Electrooptic effects due to the molecular reorientation of thin FSFLC film have been reported in previous papers.^<[1,2] In this study, an electrooptic effect of a FSFLC film that was a thickness of near helical pitch was measured and texture observation was carried out by polarizing microscope.
