Abstract
A nematic liquid crystalline composition having positive dielectric anisotropy is provided in the homeotropic texture by contact with a layer of an electrically insulating polysiloxane elastomer. An electrical field is then applied parallel to the molecular axes of the nematic resulting in reorientation of the nematic molecules.
