Abstract
A polarizer includes a substrate having a first refractive index, a metal pattern disposed on the substrate, and a passivation layer disposed on the metal pattern. The metal pattern includes a plurality of protrusions having widths. The passivation layer has a second refractive index and covers at least one surface of the protrusions.
