Abstract
An electroluminescent display substrate and a display device are provided. The electroluminescent display substrate includes: a base substrate; a display light-emitting element arranged on the base substrate; an encapsulation structure arranged on the base substrate and covering the display light-emitting element; a light-shielding structure arranged on a side of the encapsulation structure away from the base substrate; and an opening at least passing through the encapsulation structure. The light-shielding structure includes a first light-shielding portion and a second light-shielding portion that extend continuously. A vertical distance between the first light-shielding portion and the base substrate is greater than that between the light-emitting layer of the display light-emitting element and the base substrate, and a vertical distance between at least a part of the second light-shielding portion and the base substrate is less than that between the light-emitting layer of the display light-emitting element and the base substrate.
