Zusammenfassung:	A brightness enhancement film comprises a substrate, a plurality of refracting microstructures and a reinforcing layer. The substrate has a first surface and a second surface. The refracting microstructures are arranged on the first surface of the substrate, and provided for varying surface curvatures to guide and refract incident light. The reinforcing layer is coated on the second surface of the substrate, and has a hardness greater than that of the substrate so that the reinforcing layer can protect the substrate from warpage and/or abrasion.
