Liquid crystal lens

A liquid crystal lens, comprising:

• a first substrate;
• a first electrode layer disposed on the first substrate;
• a liquid crystal layer disposed on the first electrode layer;
• and
• a second electrode layer disposed on the liquid crystal layer, comprising:
• a plurality of first electrode patterns;
• a plurality of second electrode patterns respectively opposite to the first electrode patterns, and the second electrode patterns and the first electrode patterns being alternately arranged, wherein a square measure of the first 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 electrode patterns increases from the edge of the liquid crystal lens to the center of the liquid crystal lens, a square measure of the second electrode patterns decreases from the edge of the liquid crystal lens to the center of the liquid crystal lens, so that a resistance of the second electrode patterns increases from the edge of the liquid crystal lens to the center of the liquid crystal lens, a portion of each of the first and second electrode patterns has a same width, and a width of other portions of each of the first and second patterns decreases from the edge to the center of the liquid crystal lens.
