The optical lens assembly has a half of a maximum field of view of the optical lens assembly a distance from an image-side surface of the seventh lens to an image plane on an optical axis, a radius of curvature of an object-side surface of the fourth lens, and a radius of curvature of an image-side surface of the fourth lens. An appropriate configuration of a high-quality lens module with the maximum field of view and an optical back focal length can be provided, to avoid interference of the structural appearance.
