ABSTRACT:
An electro-optical cell comprises, on an optical path: front and back electrode base plates each comprising a transparent base plate having an inner surface, an electrode film provided on said inner surface, and an optically active poly-.alpha.-amino acid film provided on said inner surface over the electrode film and orientated in one direction intersecting the orientated direction of the poly-.alpha.-amino acid film of the other electrode base plate, the electrode base plates being disposed with the inner surfaces of their base plates in mutually facing state; and a nematic liquid crystal substance having a positive dielectric anisotropy and interposed between the front and back electrode base plates. Electro-optical devices can be fabricated by combining this electro-optical cell with front and back polarizers with polarization directions at specific angles relative to the orientation processed directions of the electrode base plates and by further adding a reflecting plate.
