Claim:
1. A liquid crystal lens comprising: a lower substrate; an upper substrate disposed opposite to the lower substrate; a plurality of lower lens electrodes disposed on the lower substrate and corresponding to a unit liquid crystal lens; an upper lens electrode disposed on substantially an entire surface of the upper substrate; a spacer disposed between the lower substrate and the upper substrate; and a liquid crystal layer disposed between the lower substrate and the upper substrate, wherein the lower lens electrodes comprise a flat-shaped central lens electrode disposed at a central portion thereof and having a width greater than a width of other lower lens electrodes corresponding to the unit liquid crystal lens, the lower lens electrodes comprise a plurality of branch electrodes disposed at a left side of the central lens electrode, a width each of the plurality of branch electrodes is increased as it is closer to the central lens electrode corresponding to the unit liquid crystal lens, and the spacer is disposed only on the central lens electrode.
