Abstract
An optical imaging lens sequentially includes a first lens element, a second lens element, a third lens element, and a fourth lens element along an optical axis from an object side to an image side. Each of the first lens element to the fourth lens element includes an object-side surface facing the object side and allowing imaging rays to pass through, and an image-side surface facing the image side and allowing the imaging rays to pass through. The first lens element has negative refracting power, and a periphery region of the object-side surface of the first lens element is convex. At least one of an optical axis region of the object-side surface of the second lens element and an optical axis region of the image-side surface of the second lens element is plane. The third lens element has negative refracting power or the fourth lens element has positive refracting power.
