Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To protect the polarizing film of a polarized light separating element having a polarizing film consisting of polydiacetylene and to improve the utilization efficiency of light of the element. SOLUTION: This polarized light separating element 10 is constituted by forming an oriented film 14, the polarizing film 12 consisting of the polydiacetylene and a protective film 13 in this order on a glass substrate 11 which is an optically isotropic substrate. The polarizing film 12 is formed in the part exclusive of the exposed surface 111 of the glass substrate 11.
