A lens driving device includes a lens barrel supporting a lens; an autofocusing driving unit disposed on one side of a plane perpendicular to an optical axis direction based on the lens barrel to thereby drive the lens barrel in the optical axis direction; and a hand-shake prevention driving unit disposed on sides of the plane perpendicular to the optical axis direction other than the one side on which the autofocusing driving unit is disposed, to thereby drive the lens in a direction perpendicular to the optical axis direction.
