Abstract
The present invention discloses a liquid crystal lens and a manufacturing method thereof. At least one first electrode is disposed on a first substrate, a first alignment layer is disposed on the first electrode, a liquid crystal layer is disposed on the first alignment layer, a second alignment layer is disposed on the liquid crystal layer, an electric field uniformization layer is disposed on the second alignment layer, at least one second electrode and at least one third electrode are disposed on the electric field uniformization layer, and the second electrode is arranged around the third electrode. A second substrate is disposed on the second electrode and the third electrode. The third electrode which matches up with the second electrode produces an electric field gradient and the liquid crystal layer is affected uniformly by the electric field uniformization layer so as to achieve rapid focus purpose by the liquid crystal.
