1. A display panel, comprising:
a substrate and an array layer disposed on a side of the substrate;
a light-emitting layer, wherein the light-emitting layer is on a side of the array layer away from the substrate and includes a plurality of light-emitting units; and
a color filter layer, wherein the color filter layer includes a light-blocking portion and a plurality of color resist units; the plurality of color resist units is disposed corresponding to the plurality of light-emitting units; at least two color resist units of a same color have different orthographic projection shapes on a same first plane; a first plane at least includes one of a first sub-plane and a second sub-plane; the first sub-plane is a plane perpendicular to the substrate; and the second sub-plane is a plane in parallel with the substrate, wherein
the plurality of color resist units includes a first color resist unit a surface of the first color resist unit on a side away from the substrate is a first surface; the first color resist unit includes a plurality of first grooves; and the plurality of first grooves is formed by recessing the first surface toward the side of the substrate.
