Abstract
An optical element and a method for manufacturing the optical element are described. The optical element includes a transparent substrate, an optical layer, and an adhesive layer. The optical layer is located on a surface of the transparent substrate. The optical layer has a first surface and a second surface, which are opposite to each other. The first surface is set with various diffracting optical structures. A refractive index of the optical layer is equal to or greater than 1.4. The adhesive layer is sandwiched between the surface of the transparent substrate and the second surface of the optical layer.
