Transformation of cholesteric orientational structures and optical textures induced by the electric field–driven ionic modification of surface anchoring

Abstract

The reorientation of a cholesteric liquid crystal with a large helical pitch induced by the electric field–driven modification of surface anchoring is investigated. In the initial state, the liquid crystal cell has a homeotropic alignment of the director. An applied dc electric field produced a twisted homeoplanar structure of the cholesteric.
