Abstract
A diffractive multiview backlight and a multiview display employ an array of diffractive multibeam elements including a plurality of diffraction gratings configured to provide a plurality of light beams having different principal angular directions corresponding to different view directions of the multiview display. The display includes multiview pixels that include sub-pixels. A size of the diffractive multibeam element of the array is comparable to a size of a sub-pixel in a multiview pixel of the multiview display.
