Abstract

We propose a low-driving-voltage multifocal liquid crystal (LC) lens such as a concave lens inside a convex lens. The multifocal LC lens is prepared using a glass substrate with a transparent circularly hole-patterned electrode, an additional ring electrode inside, and a center electrode. The multifocal lens properties are attained, and the focal length of the concave lens and/or convex lens can be changed by applying low voltages to the electrodes.
