Abstract

Liquid crystals subjected to an electric field are stabilized by the addition of an electrochemically active and chemically stable material capable of undergoing reversible oxidation-reduction at the electrodes applying the field to the material. The invention is particularly for use in converting electric signals to optical signals.
