Patent ID: 8692971

Claim:
A liquid crystal lens, comprising: a first substrate; a second substrate disposed opposite to the first substrate, and a space being formed between the first substrate and the second substrate; a plurality of first electrodes disposed on a side of the first substrate facing the second substrate, each of the first electrodes having a slit, wherein a gap exists between any two adjacent first electrodes, the gaps and the slits are arranged alternately; a plurality of second electrodes disposed between the first substrate and the second substrate, each of the second electrodes being substantially corresponding to a slit of a respective one of the first electrodes, and the second electrodes being not corresponding to the gaps, wherein a distance between two adjacent first electrodes is smaller than a distance between two adjacent second electrodes; an insulating layer disposed between the first electrodes and the second electrodes; a liquid crystal layer disposed between the second electrodes and the second substrate; and a third electrode disposed between the liquid crystal layer and the second substrate, wherein the second electrodes are disposed between the first electrodes and the liquid crystal layer.
