==Original Abstract Submitted==

A waveguide display system include a waveguide, an input coupler configured to couple display light into the waveguide, a first pupil expander, and a second pupil expander. The first pupil expander is configured to deflect, at a first plurality of locations along a first direction, the display light towards the second pupil expander. The second pupil expander is configured to deflect, at a second plurality of locations along a second direction different from the first direction, the display light from the first pupil expander towards an eyebox of the waveguide display system. At least one of the input coupler, the first pupil expander, or the second pupil expander includes transflective mirrors that are tilted within the waveguide such that the transflective mirrors are inconspicuous when viewed from an oblique angle.
