Abstract
Provided is an optical device including an insulation layer, a plurality of nanopatterns disposed on the insulation layer and spaced apart from each other on the insulation layer, and a medium layer covering the nanopatterns, wherein the nanopatterns include first to third nanopatterns, the first to third nanopatterns respectively include first to third different widths in a first direction parallel to a top surface of the insulation layer, and a first distance between the first nanopattern and the second nanopattern is different from a second distance between the second nanopattern and the third nanopattern.
