A liquid crystal lens element having a lens function capable of stably correcting spherical aberration containing a power component corresponding to focus change of incident light according to the magnitude of applied voltage.The liquid crystal lens element comprises a pair of transparent substrates 11 and 12, one (12) of the transparent electrodes is provided with a transparent electrode 15 and a Fresnel lens surface 17, and the other one (11) of the pair of transparent electrodes is provided with a phase correction surface 18 and a transparent electrode 16. Thus, by disposing a Fresnel lens surface 17 and a liquid crystal layer 13 between a pair of transparent electrodes 15 and 16, it becomes possible to change substantial refractive index distribution of the liquid crystal layer 13 according to the magnitude of applied voltage, and to add a positive or negative power to a wavefront transmitted through the liquid crystal layer 13, the Fresnel lens surface 17 and the phase correction surface 18.
