Each of the microstructures includes first and second convex portions and a concave portion disposed between and interconnecting the first and second convex portions, and two adjacent ones of the microstructures are connected. Intersections between the microstructures cooperatively define an imaginary plane, and a lowest point of the concave portion is disposed at one side of the imaginary plane opposite to the rear surface of the substrate.
