Abstract
A light-emitting substrate includes a substrate, and a first conductive layer, a passivation layer and a first protective pattern that are disposed on the substrate sequentially. The first conductive layer includes a plurality of pad groups each including a plurality of pads. The passivation layer is provided with a plurality of openings therein, an opening is located on a side of a pad away from the substrate, and the opening and an edge of the pad have a distance therebetween. The passivation layer includes a first climbing portion covering a sidewall of a first edge of the pad and a second climbing portion covering a sidewall of a second edge of the pad. The first protective pattern covers the first climbing portion and extends to a side of the passivation layer away from the pad, and the first protective pattern and the opening have a distance therebetween.
