Abstract
A liquid crystal lens is provided. The liquid crystal lens includes an electrode group, a touch panel and a liquid crystal layer. The electrode group includes a left electrode, a right electrode and an intermediate electrode, wherein the intermediate electrode is located between the left electrode and the right electrode. The touch panel is disposed above the electrode group. The liquid crystal layer is disposed between the touch panel and the electrode group. A voltage value of the touch panel is the same as a voltage value of the intermediate electrode, a voltage value of the left electrode is to the same as a voltage value of the right electrode. When the voltage value of the touch panel is VT*sin(wt), the voltage value of the left electrode is VL*sin(wt)+ VT*sin(wt).
