Abstract

Electric field induced deformations of chiral nematic liquid crystal layers were studied numerically. Uniformly lying helix structure of short pitch flexoelectric mixtures was considered. The electro-optic effect due to rotation of optical axis around the normal to the layer was simulated. The flexoelectric torque arising under the action of bias voltage and responsible for this rotation was calculated. It was found that the prevailing torque occurs in close vicinity of the boundary plates. Nonlinearity of superposition of splay and bend contributions to the total flexoelectric torque was found.
