OPTICAL ELEMENT AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical element that is appropriate as a wire grid polarizer or a wavelength plate and is excellent in optical characteristics.SOLUTION: An optical element 1 comprises: a translucent substrate 2; and an inorganic material layer 3 that is formed on the translucent substrate 2 and has a plurality of linear concavo-convex structures 6 in parallel with each other. The inorganic material layer 3 has a refractive index nd of 1.8 or greater.
