Abstract: A liquid crystal lens is disclosed in embodiments of the present disclosure. A liquid crystal lens includes: a first substrate and a second substrate disposed opposite to each other; a first electrode layer and a second electrode layer between the first substrate and the second substrate, the second electrode layer including a plurality of second electrodes each of which is capable being applied independently with a voltage and forms a vertical electrical field with the first electrode layer; and blue phase liquid crystals between the first electrode layer and the second electrode layer, wherein, the blue phase liquid crystals in different positions have different degrees of deformation under the action of the vertical electrical field at different intensities, to enable an imaging distance of the liquid crystal lens to vary smoothly along a preset curve. A display device and a method of driving the display device are further disclosed.
