Abstract

A substrate, a grating and a display panel are provided. The substrate comprises a plurality of sub-pixel groups arranged periodically, each of the plurality of sub-pixel groups comprises: a first type of sub-pixel group which is configured for displaying a plurality of viewpoint images and comprises a first sub-pixel unit ( 201 ) configured for displaying a first viewpoint image, a second sub-pixel unit ( 201 ) configured for displaying a second viewpoint image and a third sub-pixel unit ( 203 ) configured for displaying a third viewpoint image; each of the plurality of sub-pixel groups at least comprises a first sub-pixel column and a second sub-pixel columns; and the first sub-pixel unit ( 201 ) is located in the first sub-pixel column of each of the plurality of sub-pixel groups, the second sub-pixel unit ( 202 ) and the third sub-pixel unit ( 203 ) are located in the second sub-pixel column of each of the plurality of sub-pixel groups, the second sub-pixel column and the first sub-pixel column are adjacent to each other and are staggered a preset distance in a vertical direction, and the preset distance is smaller than a width of one sub-pixel unit. Through the arrangement of the sub-pixel units on the substrate, the viewing angle of each viewpoint image is increased, and because within each viewing angle, only the viewpoint image corresponding to the viewing angle can be seen, the interference between different viewpoint images is reduced.
