PROBLEM TO BE SOLVED: To provide a method of manufacturing optical element which improves the productivity by reducing a damage to a mold during press molding and is capable of manufacturing a low-cost optical element, and to provide a projection display device with an optical element obtained by the manufacturing method, as a polarization element. SOLUTION: A metallic glass layer 2 is disposed on a substrate 11A in the amorphous state. Then, the metallic glass layer 2 is heated to a glass transition temperature or more and, in the state that the metallic glass layer 2 is not crystallized, the mold 100 having a predetermined rugged shape is pressed on the metallic glass layer 2. In such a state, the metallic glass layer 2 is hardened, thereby, a shape corresponding to the predetermined rugged shape is transferred and the rugged shape exhibiting an optical performance is afforded to the metallic glass layer 2. Lastly, the mold 100 is stripped off from the metallic glass layer 2. COPYRIGHT: (C)2007,JPO&INPIT
