Abstract
A light-emitting substrate includes a substrate and a first light-emitting device. The first light-emitting device includes a first electrode, a first functional layer, a first light-emitting pattern and a second electrode that are sequentially disposed in a direction away from the substrate. The first functional layer is in contact with the first light-emitting pattern. The first light-emitting pattern includes a first light-emitting material. The first light-emitting material includes first light-emitting particles and first ligands combined with the first light-emitting particles. The first functional layer includes a first functional material. The first functional material includes first functional particles and second ligands combined with the first functional particles. A development characteristic of the first ligands is same as a development characteristic of the second ligands.
