Claim:
1. A liquid crystal lens, comprising: a first substrate; a second substrate, opposed to the first substrate; a liquid crystal layer, interposed between the first substrate and the second substrate; a first transparent electrode layer, located on a side of the first substrate close to the liquid crystal layer, the first transparent electrode layer comprises a plurality of strip transparent electrodes spaced apart from one another at a predetermined interval, such that a lateral electric field is formed between two adjacent strip transparent electrodes; a planarization layer, wherein the planarization layer comprises a transparent insulating resin material, has a thickness in the range from 1 μm to 5 μm, the planarization layer covers a top surface and side surfaces of the strip transparent electrodes, and located on a side of the first transparent electrode layer close to the liquid crystal layer such that the lateral electric field is weaker; a first alignment layer, located on a side of the planarization layer close to the liquid crystal layer; a second transparent electrode layer, disposed on a side of the second substrate close to the liquid crystal layer; and a second alignment layer, disposed on a side of the second transparent electrode layer close to the liquid crystal layer.
