Abstract
A method of fabricating a liquid lens which can prevent unstable movement of liquids while sealing a hole containing the liquids by applying voltage to a chamber containing the liquids to induce electrowetting, and a liquid lens fabricated thereby. The method includes providing a chamber with a hole formed therein for containing liquid and injecting two non-miscible liquids with different refractive indices. The method also includes placing a conductive transparent plate to be in contact with the liquid on the top and applying voltage to the conductive transparent plate and the chamber to induce electrowetting, thereby changing the shape of meniscus between the two liquids. The method further includes covering an upper surface of the chamber with the conductive transparent plate to seal the hole.
