Abstract
Provided are a liquid crystal lens which controls an optical path, and a display including the liquid crystal lens. The liquid crystal lens includes a first and a second electrode which face each other, a liquid crystal layer interposed between the first electrode and the second electrode and has flat top and bottom surfaces, and a dielectric layer interposed between the second electrode and the liquid crystal layer, where the dielectric layer includes a first and a second dielectric sub-layer, the first dielectric sub-layer made of a material having a different dielectric constant from that of the second dielectric sub-layer, the first dielectric sub-layer includes one or more unit patterns, a surface of each of the unit patterns includes a plurality of flat sections, and a height of each of the unit patterns in a first flat section is different from the height thereof in a second flat section.
