Claim Text:
1. A liquid crystal lens comprising: a liquid crystal layer; at least two driving electrode plates, wherein the liquid crystal layer is arranged between the adjacent driving electrode plates, and each of the driving electrode plates comprising: a transparent substrate comprising a surface; a circuit layer deposited on the surface; an insulating layer covering the circuit layer; an electrode layer deposited on the insulating layer; at least a conducting pillar arranged in the insulating layer, the pillar connected to the electrode layer and the circuit layer; and an alignment layer abutting the liquid crystal layer, wherein the electrode layer is interposed between the alignment layer and the insulating layer, wherein the electrode layer of at least one of the driving electrode plates comprises at least two ring-shaped electrodes, one of the ring-shaped electrodes encircles the other ring-shaped electrode, and the ring-shaped electrodes have the same geometric center; wherein the circuit layer of one of the at least two driving electrode plates comprises n ring-shaped electrodes and n traces, the ring-shaped electrodes connect to the traces respectively, and the traces distribute in an isometric way about the geometric center, wherein n is positive integer and is larger than 2, and the angle between two adjacent traces is 360/n degree.
