Abstract
A wire grid polarizer including a substrate, parallel conductive wire patterns which protrude from a top surface of the substrate, non-conductive wire patterns which are formed on the conductive wire patterns, respectively, and a protective layer which is formed on the conductive wire patterns and the non-conductive wire patterns. The protective layer includes first transparent particles having a diameter greater than a period of the conductive wire patterns, and spaces between the conductive wire patterns are filled with air or are evacuated to form a vacuum.
Claims17
A wire grid polarizer comprising:
- a substrate;
- conductive wire patterns extending in parallel and protruding from a top surface of the substrate;
- non-conductive wire patterns disposed on the conductive wire patterns;
- and
- a protective layer disposed on the conductive wire patterns and the non-conductive wire patterns,
- wherein:
- the protective layer comprises first transparent particles having an average diameter greater than a period of the conductive wire patterns;
- and
- spaces between the conductive wire patterns are filled with air or are evacuated to form a vacuum.
A method of fabricating a wire grid polarizer, the method comprising:
- forming a conductive material layer and a non-conductive material layer on a substrate;
- patterning the conductive material layer and the non-conductive material layer into wire patterns;
- and
- forming a protective layer, which comprises transparent particles, on the wire patterns.
