1. A display device comprising:

  • an optical display element; and

    a polymer face plate that receives or directs light to the optical display element comprising columnar areas where an index of refraction of the columnar areas is different from the index of refraction of a cladding area surrounding the columnar areas, wherein the columnar areas are formed by exposure of a photoactive resin to a light interference pattern formed by three collimated and coherent light sources, wherein the light interference pattern includes first light regions and second dark regions in the photoactive resin wherein the photoactive resin of the first light region is altered by exposure to light of the light interference pattern and wherein either the first regions or the second regions form the columnar areas.
