A concept for an electrically tunable liquid crystal (LC) lens using a hole-patterned electrode and the vertical alignment liquid crystal cell by circular photoalignment is demonstrated. The proposed LC lens is a polarizer-free negative lens(0D~-0.93D) by changing the driving voltage. The proposed LC lens can be applied for AR/VR applications.
