Polarizing element and a method for manufacturing the same

Abstract

An object of the invention is to provide a polarizing element which has a sufficiently large birefringence index and exhibits satisfactory blue-light transmittability by a simple and inexpensive method for manufacturing a polarizing element. An organic material which exhibits light transmittability and birefringence, such as PET, is stretch-processed into predetermined forms that are continuously kept uniform, thereby forming a plurality of prism sheets. These prism sheets are laminated on one another such that prism sheets having mutually different optical axes make contact with each other, thereby forming a layered structure of prism sheets. By cutting up the layered structure of prism sheets, a layered structure of optical blocks having a predetermined shape is obtained, thereby realizing a polarizing element.
