Abstract
A liquid crystal lens includes a liquid crystal layer and at least two driving electrode plates. The liquid crystal layer is arranged between the driving electrode plates. Each of the driving electrode plates includes a transparent substrate, a circuit layer, an insulating layer, an electrode layer, at least a conducting pillar and an alignment layer. The transparent substrate has a surface, and the circuit layer is atop the surface. The conducting pillar is arranged in the insulating layer and connected to the electrode layer and the circuit layer. The alignment layer contacts the liquid layer. The electrode layer is interposed between the alignment layer and the insulating layer. The electrode layer in at least one of the driving electrode plates includes at least two ring-shaped electrodes.
