摘要：The invention relates to an optical variation device (10) which includes a liquid-crystal element (12) having optical properties that control the propagation of light, twosubstrate plates (14, 16) arranged on either side of the liquid-crystal element (12), thetwo substrate plates (14, 16) being covered respectively with first (18) and second (20)control electrodes, each electrode (18, 20) having a substantially central opening (22, 24)referred to as the optical aperture, the device also comprising a layer (26, 28) of amaterial arranged between the electrodes and filling the optical aperture. The materialhas a surface resistivity of 10 kΩ/square to 10 GΩ/square and at least the first electrodeis divided into a plurality of portions forming sub-electrodes suitable for simultaneouslyreceiving different potentials.
