1. A three-dimensional display device, comprising:

  • the three-dimensional grating structure comprises a pixel structure consisting of a plurality of sub-pixels which are closely arranged, and a three-dimensional grating consisting of a plurality of strip-shaped grating structures which are periodically arranged along the horizontal direction;

    wherein the content of the first and second substances,the sub-pixels in each row of the sub-pixels are arranged in an aligned mode, the positions of half sub-pixels are staggered in the row direction between the sub-pixels in every two adjacent rows of the sub-pixels, and the color of each sub-pixel is different from that of each adjacent sub-pixel;

    the extending directions of the strip-shaped grating structures are the same and have a certain inclination angle with the horizontal direction;

    in the horizontal direction, the number of the sub-pixels in each row corresponding to each strip-shaped grating structure is three, each strip-shaped grating structure corresponds to three sub-pixels in each row of the sub-pixels, which respectively display two viewpoint images, and in each column of the sub-pixels, the display brightness of one or all of the adjacent two sub-pixels displaying different viewpoint images is lower than that of the other sub-pixels;

    the extending direction of the strip-shaped grating structure is inclined to the horizontal direction by an angle of 76 degrees, the viewpoint image displayed by each sub-pixel in the pixel structure takes every three columns of sub-pixels as a repeating unit, the repeating unit is as follows,

    or, the extending direction of the strip-shaped grating structure is inclined at an angle of 77 degrees with respect to the horizontal direction, the viewpoint image displayed by each sub-pixel in the pixel structure has every three columns of sub-pixels as a repeating unit, the repeating unit is as follows,

    or, the extending direction of the strip-shaped grating structure is inclined at an angle of 78 degrees with respect to the horizontal direction, and the viewpoint image displayed by each sub-pixel in the pixel structure has every three columns of sub-pixels as a repeating unit, which is as follows,

    or, the extending direction of the strip-shaped grating structure is inclined at 76.89 degrees with respect to the horizontal direction, the viewpoint image displayed by each sub-pixel in the pixel structure has every six columns of sub-pixels as a repeating unit, the repeating unit is as follows,
