In a structure comprising a pair of facing electrode plates and a layer of a nematic liquid crystal having a positive dielectric anisotropy, which is supported between said facing electrode plates, when each of the electrode surfaces coming into contact with the nematic liquid crystal layer is provided with a coating of poly-p-xylylene and/or its substituted product and the surface of said coating is furnished with a predetermined orientation, a liquid crystal device of the torsion effect type having good electro-optical characteristics is provided. When a layer of an epoxy resin or silane coupling agent is formed between the coating of the poly-p-xylylene type resin and the electrode surface, the adhesion of the poly-p-xylylene type resin coating is improved.
