Display panel and manufacturing method thereof, and display apparatus

A method for manufacturing a display panel, comprising:

• providing a substrate;
• forming a first pixel definition layer on a side of the substrate, wherein the first pixel definition layer comprises a first pixel opening;
• forming a second pixel definition layer on a side of the first pixel definition layer away from the substrate, wherein at least one of the first pixel definition layer and the second pixel definition layer comprises a light-shielding material, the second pixel definition layer comprises a second pixel opening, and the second pixel opening at least partially overlaps the first pixel opening along a direction perpendicular to a plane of the substrate;
• and
• forming a partition portion at least partially surrounding the first pixel opening and the second pixel opening, wherein the partition portion comprises a recessed portion or a first protrusion portion, the recessed portion is recessed from a surface of the second pixel definition layer away from the first pixel definition layer toward a direction close to the first pixel definition layer, the first protrusion portion protrudes from the surface of the second pixel definition layer away from the first pixel definition layer toward a direction away from the first pixel definition layer.

A display apparatus, comprising a display panel;

• wherein the display panel comprises:
• a substrate;
• a first pixel definition layer located on a side of the substrate, wherein the first pixel definition layer comprises a first pixel opening;
• a second pixel definition layer located on a side of the first pixel definition layer away from the substrate, wherein at least one of the first pixel definition layer and the second pixel definition layer comprises a light-shielding material, the second pixel definition layer comprises a second pixel opening, and the second pixel opening at least partially overlaps the first pixel opening along a direction perpendicular to a plane of the substrate;
• a light-emitting layer at least partially located in the first pixel opening and the second pixel opening;
• and
• a partition portion at least partially surrounding the first pixel opening and the second pixel opening, wherein the partition portion comprises a recessed portion or a first protrusion portion, the recessed portion is recessed from a surface of the second pixel definition layer away from the first pixel definition layer toward a direction close to the first pixel definition layer, and the first protrusion portion protrudes from the surface of the second pixel definition layer away from the first pixel definition layer toward a direction away from the first pixel definition layer.
