DIMMING FILM

PURPOSE:To improve contrast putting a plurality of dimming film elements one on top of another. CONSTITUTION:A high polymer liquid crystal compound film 3-2 of approximately uniform thickness is kept adjacent to the side of the electrode 2-2 of a transparent conductive film 2, and a common electrode 6 is kept adjacent to the top of the film 3-2. The common electrode 6 is available from the formation of transference electrodes 6-2 and 6-3 via the deposition of ITO(indium-tin oxide film) on both sides of a film (or glass substrate) 6-1. The transference electrode 6-3 of the common electrode 6 is laid on top of the film 3-2 and another high polymer liquid crystal compound film of approximately uniform thickness is kept adjacent to the side of the transference electrode 6-2. In addition, a transparent conductive film 1 at the face opposite the adjacent face of the film 3-1 has a transference electrode 1-2 and the compound film 3-1 adjacent to each other face to face, thereby forming dimming film.
