1. A display apparatus comprising:

  • a light modulating layer;

    a polarizer; and

    a light directing film, comprising;

    a prismatic structure having two sides, one side including saw-tooth formations having tilted surfaces;

    a metal layer on the side of the prismatic substrate having the saw-tooth formations;

    an inorganic protective layer formed on the metal layer, wherein the inorganic protective layer inhibits molecular transfer to the metal layer; and

    a pressure sensitive adhesive layer between the polarizer and the inorganic protective layer;

    wherein the display apparatus has a glare angle at which front surface glare is viewed and wherein a tilt angle of the tilted surfaces offsets an optimal viewing angle for the display from the glare angle;

    wherein the inorganic protective layer protects the metal layer and balances the color of reflected and transmitted light.
