    摘要： A liquid zoom lens mounted on a portable terminal is provided. In the liquid zoom lens, a cylindrical body has upper and lower openings to which one pair of lenses is coupled. An auto-focus lens part includes a first insulating liquid layer, a first electrolyte layer, and a first lens. The first insulating layer and the first electrolyte layer are disposed to form an interface at a lower portion of the body. The first lens is disposed on the first electrolyte layer and has a periphery closely attached to a lower portion of an inner periphery of the body. An optical zoom lens part includes a second insulating liquid layer, a second electrolyte layer, and a second lens. The second insulating liquid layer and the second electrolyte layer are disposed to form an interface on the first lens. The second lens is fixed to be movable within the second insulating liquid layer, such that a periphery is closely attached to the inner periphery of the body. Accordingly, the auto-focus function and the optical zoom function can be simultaneously achieved through a single liquid lens whose curvature is varied by the difference of the inherent refractive index between the electrolyte and the insulating liquid.
