Preparation of a cholesteric liquid crystalline phase in planar orienting liquid crystal cells exhibits

Abstract

Preparation of a cholesteric liquid crystalline phase in planar orienting liquid crystal cells exhibits discontinuous colour changes with temperature when viewed between crossed polarizers. The trans­ mission spectra of such a system can be described by a modified de Vries equation, with the bire­ fringence dispersion included in a simplified single-band… (More)
