Abstract
The invention concerns an electrowetting optical device comprising a chamber (15) comprising first and second immiscible liquids (16, 18) contacting each other at a liquid-liquid interface (19), the first liquid being an insulating liquid and the second liquid being a conducting liquid; a first electrode (20) in the contact with the second liquid; and a second electrode (202) insulated from the first and second liquids by an insulating layer, wherein the second electrode is formed of a conductive molded polymer material, wherein the curvature of said liquid-liquid interface is controllable by application of a voltage between said first and second electrodes.
