Abstract:
1. A liquid crystal lens, comprising: a first substrate; at least one first electrode disposed on the first substrate; a first alignment layer disposed on the at least one first electrode; a liquid crystal layer disposed on the first alignment layer; a second alignment layer disposed on the liquid crystal layer; an electric field uniformization layer disposed on the second alignment layer, arranged for maintaining a substantially smooth electric field gradient in order to affect unity of the liquid crystal layer so as to achieve rapid focusing and reducing a working voltage of the liquid crystal layer; at least one second electrode disposed on the electric field uniformization layer; at least one third electrode disposed on the electric field uniformization layer, and the at least one second electrode arranged around the at least one third electrode; and a second substrate disposed on the at least one second electrode and the at least one third electrode; wherein the smooth electric field gradient is produced by the second electrode and the third electrode.
