Abstract
A variable optical device array includes: a transparent substrate; an addressing layer including an electrode wire arranged on the transparent substrate; a barrier wall portion disposed on the addressing layer to define cell regions and including conductive barrier walls that are electrically connected to the electrode wire, wherein pairs of the conductive barrier walls are arranged to form double walls; an insulation material filling a region between each pair of conductive barrier walls; a conductive first fluid and a nonconductive second fluid disposed in each of the cell regions, wherein the first and second fluids are not mixed; an insulation coating layer disposed on a top surface of each of the conductive barrier walls and on side surfaces of each of the cell regions; a transparent electrode layer covering the cell regions; and a voltage applying unit to apply a voltage between the transparent electrode layer and the addressing layer.
