Abstract: A manufacturing method of a light-emitting substrate and a display device are provided. The manufacturing method includes: providing a substrate provided with a plurality of electrodes, forming a patterned photoresist layer including openings exposing the electrodes on a surface of the substrate, forming connecting parts in the openings, removing the patterned photoresist layer, and bonding a plurality of light-emitting elements on the connecting parts, wherein slope angles of a plurality of connecting part sidewalls of the connecting parts are ranged between 40° and 140°. The method could improve a yield rate of light-emitting elements bonded to electrodes through connecting parts.

Abstract: A display panel is provided, including a grounding signal wiring, driving chips, a driving chip input output signal wiring, and a power line. A grounding signal pin is connected to the grounding signal wiring. The driving chip input output signal wiring is configured to connect a stage-transfer signal input pin and a stage-transfer signal output pin of two adjacent driving chips. The grounding signal wiring, the driving chip input output signal wiring, and the power line are disposed in a same layer and do not intersect with each other.
