Liquid lens and camera module

The invention provides a liquid lens and a camera module. Two layers of conductive liquid and insulating liquid are filled in a closed cavity to form two interfaces, common electrodes are arranged atthe two ends of the closed cavity respectively, a plurality of driving electrodes are arranged on the peripheral side of the closed cavity respectively, and the driving electrodes are arranged into two groups at intervals in the axial direction of the closed cavity. The curvature of the corresponding interface can be adjusted by adjusting the electric field between each group of driving electrodesand the adjacent common electrode, so that large-range focusing is realized; by adjusting the electric field between one driving electrode and the adjacent common electrode, the curvature of the area, corresponding to the driving electrode, of the adjacent interface can be adjusted, then the electric field between each driving electrode and the adjacent common electrode can be adjusted, and the deflection angle of the opt
