Paper Abstract

A new electro-optic effect in an optically active nematic chiral structure beyond Mauguin's region has been studied. This structure rotates the polarization plane of incident light, and a liquid crystal with positive dielectric anisotropy sandwiched between crossed polarizers is switched from transparent into dark state in electric field. The characteristic features of this structure are: (a) the absence of oscillations in the transmission-voltage characteristics, (b) low demands on surface conditions (including nonrubbed cells), (c) the ability to function in any position between crossed polarizers, and (d) wide viewing angle.
