1. A polarizer, comprising:
a plurality of metal lines each extending in one direction and being arranged at regular intervals; and a plurality of low reflection layers on the plurality of metal lines, the plurality of low reflection layers contacting respective upper parts of the plurality of metal lines and having an interval and a width about equal to an interval and a width of the plurality of metal lines, wherein: the interval of the plurality of metal lines is smaller than a wavelength of a visible ray, light incident from an upper side of the plurality of low reflection layers is reflected with reflectivity equal to or smaller than 10%, each low reflection layer of the plurality of low reflection layers is a dual layer of a first low reflection layer and a second low reflection layer, the first low reflection layer contacts an upper part of the metal line and the second low reflection layer contacts an upper part of the first low reflection layer, the first low reflection layer includes CuNx, MoNx, GZO, AZO, MoOx, or CuOx, the second low reflection layer includes a metal, AlNx, TiNx, SiNx, CuNx, or MoNx, and the material of the first low reflection layer is different from the material of the second low reflection layer. |
