Abstract
A polarizing element includes a substrate; a plurality of protruded threads formed on one of surfaces of the substrate in a rough stripe pattern when viewed two-dimensionally, each of the protruded threads having a side surface forming a slope inclined with respect to the one surface of the substrate; and a plurality of metal thin wires each formed on the slope of the each protruded thread so as to be cantilever-supported by the slope and each extended in an extension direction of the protruded thread.
Claims9
A polarizing element, comprising:
- a substrate;
- a plurality of protruded threads formed on one of surfaces of the substrate in a rough stripe pattern when viewed two-dimensionally, each of the protruded threads having a side surface forming a slope inclined with respect to the one surface of the substrate;
- and
- a plurality of metal thin wires each formed on the slope of the each protruded thread so as to be cantilever-supported by the slope and each extended in an extension direction of the protruded thread.
A method for producing a polarizing element that includes a plurality of protruded threads formed on one of surfaces of a substrate in a rough stripe pattern when viewed two-dimensionally and a mask formed on an upper portion of each of the protruded threads, the method comprising:
- forming a plurality of metal thin wires each extended along the each protruded thread, each of the metal thin wires being made of a metal material deposited both on one of side surfaces of the protruded thread and on one side surface of the mask adjacent to the one side surface of the protruded thread;
- and
- removing the mask.
