A polarization‐independent blue‐phase liquid crystal lens array using multi‐electrodes is proposed. A high dielectric constant layer helps to smoothen out the horizontal electric field and reduce the operating voltage. With multi‐electrodes and a planar top electrode, the gradient electric fields are generated, and the lens‐like phase profile is obtained. When the applied voltage is changed, the focal length of the lens can be tuned from ∞ to 6.7 mm. Besides, the simulation results show that the lens is insensitive to polarization while keeping parabolic‐like profile.
