Abstract

A liquid crystal lens includes a plurality of first stripe-shaped electrodes, a plurality of second stripe-shaped electrodes, and a plurality of third stripe-shaped electrodes. Each first stripe-shaped electrode is disposed between any two of the second stripe-shaped electrodes that are adjacent to each other, and each second stripe-shaped electrode and each first stripe-shaped electrode are arranged along a first direction alternately. The third stripe-shaped electrodes are arranged along a second direction sequentially and interlaced with the first stripe-shaped electrodes and the second stripe-shaped electrodes. Any two of the second stripe-shaped electrodes and two opposite sides of each third stripe-shaped electrode perpendicular to the second direction define a lens region.
