A method for forming a display device including generating a face plate element
by providing a first substrate with a photoactive resin thereon and exposing the
photoactive resin to a light interference pattern formed by three collimated and
coherent light sources, resulting in columnar features. A display device including
an optical display element and a polymer face plate that receives or directs light
to the optical display element. The face plate includes 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. The columnar areas are formed
by exposure of a photoactive resin to a light interference pattern formed by three
collimated and coherent light sources. A method of manufacturing a wave guide including
providing a first substrate with a photoactive resin thereon and creating a wave
guide channel in a wave guide template. The wave guide channel is filled with a
liquid crystal material that is exposed to a light grating to create a variation
in an index of refraction of the liquid crystal material in the wave guide channel.
