Abstract

A liquid crystal lens includes a liquid crystal layer, a first electrode layer, a second electrode layer, transparent substrates. The second electrode layer includes multiple electrode units arranged sequentially from a position adjacent to a center thereof r toward a position away from the center thereof. Each of the electrode units includes at least one conductive line which extends from a first position of the electrode unit to a second position of the electrode unit. A distance between the second position and the center of the second electrode layer is greater than a distance between the first position and the center of the second electrode layer. A spacing distance between adjacent conductive lines is less than or equal to 100 μm. A way of driving the liquid crystal lens is simple, and an ideal potential distribution can be obtained and not affected by change of characteristics of a high-resistance film.
