Abstract

An active lens includes: a first nanoelectrode unit; a second nanoelectrode unit formed to face the first nanoelectrode unit; and a liquid crystal layer disposed between the first nanoelectrode unit and the second nanoelectrode unit. Liquid crystal molecules of the liquid crystal layer are aligned according to an electric field formed by a voltage applied to the first and second nanoelectrode units to form a refractive power.
