An exemplary embodiment of the present invention provides a driving method of a liquid crystal lens panel, including a driving method of a liquid crystal lens panel that includes a first plate including a first region, a second region, and first electrodes at the first region and the second region; a second plate facing the first plate and including second electrodes that face the first electrodes; and a liquid crystal layer between the first plate and the second plate to include a plurality of liquid crystal molecules, including: forming a backward phase slope by applying a first driving signal to the first electrodes and the second electrodes which correspond to the first region; and forming a forward phase slope by applying a second driving signal that is different from the first driving signal to the first electrodes and the second electrodes which correspond to the second region.
