ABSTRACT:
A liquid crystal element has a pair of opposed substrates, electrodes thereon, and a ferroelectric liquid crystal sealed between the substrates. A film of a conductive organic compound or a mixture of a conductive organic compound and another organic compound is disposed on the substrate surface, optionally via an orienting film. The conductive organic compound is typically a charge-transfer complex. The film may be formed by an LB method, coating, vapor phase polymerization or electrolytic polymerization. The element has improved optical bistability, contrast, and response.
