Abstract

We propose a liquid crystal (LC) lens with a new electrode structure of double circularly hole-patterned electrodes and external flat electrode for improving the optical properties such as a lens power and effective diameter with the optimum lens property. The lens power of the proposed LC lens is about 2.1 times as large as that of the previous LC lens with a single circularly hole-patterned electrode.
