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. 衍射多视图背光体和多视图显示器采用包括多个衍射光栅的衍射多束元件阵列，其中衍射光栅被配置为提供多个具有不同主角方向的光束，该不同主角方向对应于多视图显示器的不同视图方向。显示器包括具有子像素的多视图像素。阵列中的衍射多束元件的尺寸与多视图显示器的多视图像素中的子像素的尺寸相当。
