A display apparatus comprises a 2D display panel (22) and a grating (27) located on a light-emitting surface of the 2D display panel (22). A first support layer (24) is arranged between the 2D display panel (22) and the grating (27), the first support layer (24) comprises multiple first support bodies (241) with a same height, and black matrix fringes in the 2D display panel cover a length direction of the first support bodies (241). The first support layer (24) comprising the multiple first support bodies (241) with the same height enables a space between the grating (27) and the 2D display panel (22) to be kept uniform. The BM fringes in the 2D display panel (22) cover the length direction of the first support bodies (241), thereby reducing moire fringes.
