A large-aperture liquid crystal (LC) lens with low driving voltage and reduced haze was demonstrated. The root cause of haze owing to orientation fluctuations was discussed. Theoretical and experimental results confirm that the elastic constant and the electric field help to minimize the haze. The haze was reduced 50% after considering the materials and applied electric field. The improved imaging quality and MTF results of the LC lens were also demonstrated. The driving voltage was reduced from 80 V_rms to 18 V_rms by removing the typical buffering layer. The applications of such a LC lens are eyeglasses, head-mounted displays, and near eye displays.
