An optical imaging lens may include a first, an aperture stop, a second, a third, a fourth, and a fifth lens elements positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surface of the lens elements, the optical imaging lens may have improved imaging quality, enlarged half field of view and reduced surface area in front of the optical imaging lens while the optical imaging lens may satisfy AAG/T5≤1.400 and HFOV≥50.000°, wherein a sum of the four air gaps from the first lens element to the fifth lens element along the optical axis is represented by AAG, a thickness of the fifth lens element along the optical axis is represented by T5, and a half field of view of the optical imaging lens is represented by HFOV.
