Abstract
A liquid crystal lens liquid crystal lens includes: a first substrate and a second substrate; a liquid crystal layer including a plurality of liquid crystal lens units; a first electrode including a plurality of independent sub-electrodes, and there are sub-electrodes at adjacent positions of adjacent liquid crystal lens units; a second electrode being a planar electrode, the first electrode and the second electrode are configured to form an electric field to drive liquid crystal molecules of the liquid crystal layer to rotate, and adjust the curvature of the liquid crystal lens units; a first planar layer located on the side of the first electrode facing the liquid crystal layer, the first planar layer being configured to smooth an intensity variation curve of the electric field of the liquid crystal lens units; and a light-shielding layer located between the first substrate and the second substrate.
