    Abstract: An optical assembly, a display device and a method for driving the same are provided. The optical assembly includes two substrates disposed opposite to each other, and electrodes are disposed on the two substrates respectively. Voltages are applied to the electrodes to form a transverse electric field being configured for driving liquid crystal molecules proximal to the substrates to deflect, so that liquid crystal proximal to the two substrates both form liquid crystal lenses, thereby forming a double-layer liquid crystal lens structure. Since the two substrates of a liquid crystal cell have high alignment accuracy, the electrodes on the two substrates are consistent in spatial distribution, thereby solving mura problem.
