Abstract

An optical imaging lens including a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, and a seventh lens element arranged in sequence from an object side to an image side along an optical axis is provided. Each lens element includes an object-side surface and an image-side surface. An optical axis region of an image-side surface of the first lens element is concave. A periphery region of an image-side surface of the third lens element is convex. An optical axis region of an object-side surface of the fourth lens element is convex, a periphery region of an object-side surface of the fourth lens element is concave, and an optical axis region of an image-side surface of the fourth lens element is concave. An optical axis region of an image-side surface of the fifth lens element is a concave.
