Abstract
Provided is an optical element which has a retarder layer that achieves uniform retardation despite a non-planar optical surface of the optical element and which does not require complicated steps for fabrication. The optical element 10 includes a substrate 11 having a non-planar optical surface 11a, and a retarder layer 12 on the optical surface 11a. The retarder layer 12 has a uniform retardation value throughout the layer and is composed of a single layer. The optical element 10 may lack a molecule alignment mechanism to promote retardation in the retarder layer 12.
