Abstract: A curved grating structure, a display panel and the display device are provided. The curved grating structure includes multiple grating strips spaced from each other. Grating intervals between adjacent grating strips are successively decreased from a center point of the curved grating structure to a terminal of the curved grating structure. The grating interval between two adjacent grating strips is a distance in a first direction between center points of the two adjacent grating strips, and the first direction is a direction perpendicular to a normal vector of the curved grating structure passing through a center point of the curved grating structure.

Abstract: A slit grating and a three-dimensional (3D) display apparatus including the slit grating are disclosed herein, the slit grating includes a plurality of grating structures (11-17) arranged side by side. The widths of the grating structures (11-17) increase and then decrease, along the direction in which the grating structures (11-17) are arranged. A grating structure (13,14) having the largest width may define a trend change point after which the trend in the widths of the grating structure widths changes.
