A display panel includes a pixel definition layer on a base substrate, having a plurality of first apertures extending there-through; a light emitting layer at least partially in the plurality of first apertures; an encapsulating layer on a side of the pixel definition layer and the light emitting layer away from the base substrate; a bank layer on a side of the encapsulating layer away from the base substrate, having a plurality of second apertures extending there-through; and a color conversion layer at least partially in the plurality of second apertures. The color conversion layer comprises a plurality of color conversion blocks. A minimum height of a bottom of the bank layer with respect to a surface of the base substrate is greater than a minimum height of a bottom of a respective color conversion block with respect to the surface of the base substrate.
