[0088] As an important optical element, the basic principle of the liquid crystal lens is to control the voltage of the electrodes on both sides of the liquid crystal layer of the lens device, so that the edge of the electrode generates an uneven lateral electric field, so that the refractive index of the liquid crystal relative to the edge of the electrode occurs. Change, and then deflect the propagation direction of the light, and realize the function of the liquid crystal lens that the light converges or diverges.
[0089] A preparation process of a liquid crystal lens device is as follows: the liquid crystal lens device includes a first substrate and a second substrate arranged oppositely, and a liquid crystal layer located between the first substrate and the second substrate; the first substrate includes a first electrode layer The second substrate includes a second electrode layer; the first electrode layer includes a plurality of first electrodes arranged at intervals; f...
