Abstract
A retardation layer includes plurality of regions different in retardation. A retardation plate includes a substrate and a solidified liquid crystal layer supported by the substrate. The solidified liquid crystal layer is a continuous film made of a same material, and has biaxial optical anisotropy. The solidified liquid crystal layer includes plurality of regions, the regions being different in an in-plane retardation and a thickness direction retardation.
