Abstract: An optical device includes a first electrode layer, a first alignment layer, a liquid crystal layer, a second alignment layer, and a second electrode layer being arranged in turn along a light transmission direction; wherein the first electrode layer comprises a first electrode, a second electrode, and a first impedance membrane arranged between the first electrode and the second electrode, and the first electrode and the second electrode are respectively arranged on opposite ends of the first impedance membrane; the second electrode layer has a structure similar to that of the first electrode layer. The four electrodes form a light transmission hole being shaped as a parallelogram. The present invention solves the problem that the focal length of the liquid crystal lens cannot be accurately adjusted due to the instability of the impedance of the impedance membrane of the present liquid crystal lens.
