Abstract
A light-emitting substrate includes a substrate and a plurality of light-emitting assemblies. The plurality of light-emitting assemblies are located on a side of the substrate. At least one light-emitting assembly includes a light-emitting element and a light adjustment portion arranged around the light-emitting element. The light adjustment portion includes a plurality of sub-structures spaced apart from each other. In any two sub-structures in the light adjustment portion in any direction away from the light-emitting element, a height of a sub-structure closer to the light-emitting element is less than a height of a sub-structure farther from the light-emitting element.
