Techniques are described in which a view control layer is optically coupled to a waveguide having one or more diffraction structures. The view control layer selectively prevents light rays from interfacing with at least one diffraction structure of the waveguide based on a respective angle of incidence at which the light rays encounter the view control layer. In various embodiments, the view control layer may include a light control film, a polarization stack, and/or a dielectric stack angular filter.
