Abstract
This invention relates to a liquid crystal lens and a display device, and the liquid crystal lens includes a first substrate, a second substrate, a first electrode unit, plural electrode units, and a liquid crystal layer. Liquid crystal molecules corresponding to the electrode units form a plurality of lenses under the effect of a controlled electric field produced by the second electrode unit and the first electrode unit, and at least some of the lenses have different structures.
