Abstract
A liquid crystal lens which controls an optical path and a display which includes the liquid crystal lens. The liquid crystal lens includes a first electrode and a second electrode facing each other, a liquid crystal layer interposed between the first electrode and the second electrode and having flat top and bottom surfaces, and a dielectric layer interposed between the second electrode and the liquid crystal layer. The dielectric layer includes a section in which capacitance between top and bottom surfaces of the dielectric layer changes along a horizontal direction.
