Abstract: The present invention has an object to provide a production method that can prevent side etching and delamination of an anisotropic dye coating formed by an application process, thereby providing a polarizing element that exhibits durable performance and rugged reliability and that is less affected by a solvent or the like used in a production process after formation of the anisotropic dye coating, which leads to improved flexibility of the production process. The present invention also provides a polarizing element that includes a substrate, an anisotropic dye coating, and a resin composition layer, wherein the anisotropic dye coating and the resin composition layer are sequentially layered on the substrate, wherein the top surface and all side surfaces of the anisotropic dye coating are covered with the resin composition layer, and wherein the anisotropic dye coating and the resin composition layer are not formed on portions of the substrate.
