The multiview backlight includes a light guide and the microstructured multibeam element adjacent and external to a surface of the light guide. The microstructured multibeam element has an input aperture configured to receive a portion of guided light from the light guide and an output aperture configured to emit the plurality of directional light beams. The microstructured multibeam element comprises a microstructure having an interior surface configured to reflect the received guided light portion to provide the plurality of directional light beams at the output aperture. The multiview display includes the multiview backlight and an array of multiview pixels configured to provide different views of the multiview display.
