A backlight and a multiview display employ a light guide having angle-preserving scattering feature and a tapered collimator. The angle-preserving scattering feature is configured to scatter a portion of guided light out of the light guide as emitted light. The tapered collimator is configured to collimate light provided by a light source as collimated light and to communicate the collimated light to the light guide to be guided as the guided light. The collimated light has a collimation factor configured to provide a predetermined angular spread of the guided light, the collimation factor being a function of a taper of the tapered collimator. The multiview display includes multiview pixels that include view pixels as well as the angle-preserving scattering feature that includes a multibeam element having a size that is comparable to a size of a view pixel.
