1. A three-dimensional display device, comprising:
a display panel comprising a plurality of pixels sequentially arranged in a row direction and a column direction; and
a light splitting assembly arranged on a display side of the display panel and comprising a plurality of light splitting structures, the light splitting structures are parallel to each other and sequentially arranged in the row direction, wherein
pixels of the display panel covered by at least one of the light splitting structures are divided into at least one pixel repeating unit, and the at least one pixel repeating unit is sequentially arranged along an extension direction of the at least one of the light splitting structures; light emitted by pixels at same position in all of the pixel repeating units forms a viewpoint through respective corresponding light splitting structures; and
a width, in the row direction, of an orthographic projection of each of the light splitting structures on a plane where the display panel is located is D, each of the pixel repeating units comprises at least two rows of pixels, each row of pixels comprises N1 pixels, and N1 and D meet a following formula:
