An electrowetting optical device comprising: a non-aqueous conductive liquid and a non-conductive liquid, said liquids being non-miscible; and a dielectric enclosure on which both liquids are in contact and form a triple interface, wherein the non-aqueous conductive liquid comprises: a non-ionic polar organic solvent, and at least 2 weight % of a first compound; wherein the first compound is non-aqueous and is ionic or non-ionic; and wherein, if the first compound is non-ionic, the first compound is more polar than the solvent, the polarity of the non-ionic first compound being measured by Hansen parameters, a sum of the Hansen parameter for polarity (´ p ) and of the Hansen parameter for hydrogen bonding (´ h ) being higher than the sum of the corresponding Hansen parameters of the non-ionic polar organic solvent, and the non-aqueous conductive liquid further comprises an ionic second compound. |
