Abstract
There is provided a liquid lens in which a voltage is applied to control the shape of the interface between a polar liquid and a nonpolar liquid so as to control a transmitted light path at the interface. The liquid lens has a cavity with a polygonal upper side, into which the polar liquid and the nonpolar liquid are injected to form the interface.
