Abstract
A liquid crystal lens, a display device and a driving method of the display device are disclosed. The liquid crystal lens includes a first substrate, a second substrate, and a driving electrode layer and blue phase liquid crystals disposed between the first substrate and the second substrate; the driving electrode layer includes driving electrodes, each driving electrode includes at least two electrode pairs, the electrode pair includes two sub-electrodes which are disposed opposite to each other and can be applied with a voltage separately, and all the sub-electrodes in the same driving electrode are insulated from each other; the sub-electrodes of different electrode pairs in the same driving electrode are unparallel to each other; and the blue phase liquid crystals at different positions have deformations of different degrees in electrical fields with different intensities generated by the different sub-electrodes.
