The invention relates to the technical field of stereoscopic display, and discloses a liquid crystal lens, a stereoscopic display device, and an intelligent terminal. The liquid crystal lens comprisesa first substrate and a second substrate arranged in an opposite manner, and a liquid crystal layer arranged between the first substrate and the second substrate, the first substrate is provided witha first electrode layer, the first electrode layer comprises a plurality of first bar-shaped electrodes arranged at intervals, the second substrate is provided with a second electrode layer, the second electrode layer comprises a common electrode, and micro-electrode structures are arranged between two adjacent first bar-shaped electrodes at edges of the first electrode layer. When the liquid crystal lens is in a light-splitting mode, a voltage driver respectively applies a first driving voltage and a second driving voltage to the first bar-shaped electrodes and the micro-electrode structuresand applies a second voltage to the common electrode, and the deflection of liquid crystal molecules is driven to respectively form first liquid crystal lens units and second liquid crystal lens units arranged in an array manner near the first bar-shaped electrodes and the micro-electrode structures so that jaggies at edges of the liquid crystal lens can be effectively weakened or even eliminated, and the user experience is enhanced.
