A waveguide display element includes a waveguide comprising two opposing main surfaces, a first optical element arranged at a first location of the waveguide, a second optical element arranged at a second location of the waveguide, and at least one reflector surface extending between said main surfaces and adapted to reflect light rays propagating within the waveguide. The reflector surface is adapted to redirect light rays from the first optical element to the second optical element.
