The liquid lens driving mechanism includes a fixed portion, a movable portion and a driving assembly. The movable portion is movably connected to the fixed portion. The liquid lens assembly includes a liquid lens element, a fixing member and a deforming member. The fixing member is disposed on a first fixed portion surface of the fixed portion, and the deforming member is disposed on a movable portion surface of the movable portion. The movable portion surface and the first fixed portion surface face the same direction, and when the movable portion is driven by the driving assembly to move relative to the fixed portion, the liquid lens element is deformed by the deforming member, causing the optical properties of the liquid lens element to change.
