Abstract:
1. A liquid crystal lens comprising: a first substrate; a second substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a first electrode layer disposed between the first substrate and the liquid crystal layer; a second electrode layer disposed between the second substrate and the liquid crystal layer, the second electrode layer comprising a plurality of floating second electrodes; a third electrode layer disposed between the second electrode layer and the second substrate, the third electrode layer comprising a plurality of third electrodes, each of the second electrodes covering a location of at least one of the third electrodes to form a plurality of driving units, the driving units being arranged along a direction, wherein the liquid crystal layer is driven by the first electrode layer, the second electrode layer, and the third electrode layer, such that a refractive index of the liquid crystal layer is first decreased and then increased along the direction to define a lens unit; and an insulating layer disposed between the second electrode layer and the third electrode layer.
