Abstract
A liquid crystal lens including a first substrate, a first electrode layer, a liquid crystal layer and a second electrode layer is provided. The second electrode layer includes a plurality of first electrode patterns and a plurality of second electrode patterns. The second electrode patterns are opposite to the first electrode patterns, respectively, and the second electrode patterns and the first electrode patterns are alternately arranged. A square measure of first or second electrode patterns decreases from an edge of the liquid crystal lens to a center of the liquid crystal lens, so that a resistance of the first or second electrode patterns increases from the edge to the center of the liquid crystal lens.
