ABSTRACT:
A polarizing optical device has first and second major surfaces. The polarizing optical device is provided at the first major surface thereof with extrafine structures made of a metal and arranged in a specific direction. The extrafine metal structures are provided at surfaces thereof with a metal compound part, the metal compound part being formed by performing surface treatment on the surfaces of the extrafine metal structures. When light is incident from the first major surface side, light polarized in a direction parallel to the specific direction is absorbed, and light polarized in a direction perpendicular to the specific direction is transmitted. When light is incident from the second major surface side, light polarized in the direction parallel to the specific direction is reflected, and light polarized in the direction perpendicular to the specific direction is transmitted.
