7. A method for manufacturing a polarizer, comprising:
-
disposing a metal layer on a base substrate; disposing a mask pattern having a wire grid array shape on the metal layer; oxidizing an exposed upper portion of the metal layer to form a metal oxide pattern; removing the mask pattern; and patterning the metal layer by using the metal oxide pattern as a mask to form a wire grid array including a plurality of linear patterns. - View Dependent Claims (8, 9, 10, 11, 12, 13)
