• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

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.
