1. A display panel, comprising an array substrate and a cell-assembled substrate arranged oppositely to the array substrate, wherein spacers spaced from each other are arranged between the array substrate and the cell-assembled substrate, and the spacers comprise a plurality of primary spacers and a plurality of secondary spacers,
wherein M, in number, of the primary spacers are provided per unit area in a peripheral region of the display panel; and N, in number, of the primary spacers are provided per unit area in a central region of the display panel, and M is greater than (>) N;
wherein the peripheral region and the central region of the display panel are also provided with corresponding secondary spacers, a height of each of the primary spacers is greater than that of each of the secondary spacers, and a height of each corresponding primary spacer in the peripheral region is greater than that of each corresponding primary spacer in the central region.
