Abstract:
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.
