Abstract
Embodiments described herein relate to display devices, e.g., virtual and augmented reality displays and applications. In one embodiment, a planar substrate has stepwise features formed thereon and emitter structures formed on each of the features. An encapsulating layer is disposed on the substrate and a plurality of uniform dielectric nanostructures are formed on the encapsulating layer. Virtual images generated by the apparatus disclosed herein provide for improved image clarity by reducing chromatic aberrations at an image plane.
