Abstract: A display panel is provided. The display panel includes a bank layer and a quantum dots material layer on a base substrate. The bank layer defines a plurality of bank apertures. The quantum dots material layer includes a plurality of quantum dots blocks respectively in at least some of the plurality of bank apertures. At least a portion of the bank layer between two adjacent bank apertures includes a first surface, a second surface opposite to the first surface, a third surface connecting the first surface and the second surface closer to a first bank aperture, and a fourth surface connecting the first surface and the second surface closer to a second bank aperture. At least a portion of a third surface or a fourth surface of a portion of the bank layer between two adjacent bank apertures is a wavy surface including alternating convex and concave portions.
