Abstract
An optical imaging lens includes a first lens element to a seventh lens element, and each lens element has an object-side surface and an image-side surface. The second lens element has negative refracting power, and a periphery region of the object-side surface of the second lens element is convex, a periphery region of the object-side surface of the third lens element is concave, the fourth lens element has negative refracting power, an optical axis region of the object-side surface of the fourth lens element is concave, an optical axis region of the image-side surface of the fifth lens element is concave, and an optical axis region of the image-side surface of the sixth lens element is convex. Lens elements included by the optical imaging lens are only the seven lens elements mentioned above, and the following relationships: V2+V3+V5≥120.000 and (T1+L4IL7I)/(T2+G23+T3)≥3.000 are satisfied.
