A display waveguide configured for conveying image light to a viewer has a waveguide body whose refractive index varies in the thickness direction to include a high-index region between lower-index regions. Multi-layer and gradient index implementations are described. The waveguide transmits a portion of image light within the high-index region of the waveguide to provide a wider field of view.
