The present invention discloses a lens driving device which includes a lens holder defining an optical axis and being for holding a lens; a first AF coil disposed with respect to the lens holder; an OIS coil structure having two coils respectively disposed by two sides of the lens holder on a first plane having a normal direction parallel to the optical axis; two magnets respectively disposed with respect to the respective coils and having a first surface facing the first AF coil and a second surface facing the OIS coil structure; and a circuit structure connected electrically to the OIS coil structure and taking control thereof. At least one of the two magnets and the first AF coil cooperate to drive the lens holder along the optical axis, and each of the two magnets and the OIS coil structure cooperate to drive the lens holder along a direction perpendicular to the optical axis.
