Abstract

A display panel is provided. The display panel includes a base substrate; a separation structure on the base substrate; a recess extending into the separation structure; a color filter on a side of the separation structure away from the base substrate; and a lens layer including a plurality of lenses and on a side of the color filter away from the base substrate. An orthographic projection of a respective lens on the base substrate partially overlaps with an orthographic projection of the separation structure on the base substrate. The recess includes a first recess portion and a second recess portion connected with each other. In plan view of the display panel, a gap between two adjacent lenses of the plurality of subpixels is in a region at least partially overlapping with a region having both the first recess portion and the second recess portion.
