1. A direct view display apparatus, comprisinga source of backlight;

  • a liquid crystal array;

    a wire grid polarizer disposed between the source of backlight and the liquid crystal array, wherein the wire grid polarizer includes a plurality of spaced-apart metal lines on a polymer substrate, wherein the plurality of spaced-apart metal lines is characterized by a periodicity that is less than λ

    /3, where λ

    is a wavelength for visible light; and

    a second polarizer, wherein the liquid crystal array is disposed between the wire grid polarizer and the second polarizer, wherein the second polarizer is configured to transmit light transmitted by the wire grid polarizer.
