Liquid crystal lenses with the hole-patterned electrodes are widely applied for imaging applications due to the simple structure and ease of fabrication. A polarizer-free and disclination-free LC lens with positive and negative focus length is demonstrated by using four hybrid-aligned nematic LC layers with hole-patterned electrodes and dual-frequency LC materials.
