1. An electroluminescent display substrate, comprising:
a base substrate;
a display light-emitting element arranged on the base substrate, wherein the display light-emitting element comprises a light-emitting layer for emitting light;
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,
wherein an orthographic projection of the light-shielding structure on the base substrate is located between an orthographic projection of the light-emitting layer of the display light-emitting element on the base substrate and an orthographic projection of the opening on the base substrate, and
wherein the light-shielding structure comprises a first light-shielding portion and a second light-shielding portion that extend continuously, the base substrate comprises a first surface close to the display light-emitting element and the light-shielding structure, a vertical distance between the first light-shielding portion and the first surface of the base substrate is greater than a vertical distance between the light-emitting layer of the display light-emitting element and the first surface of the base substrate, and a vertical distance between at least a part of the second light-shielding portion and the first surface of the base substrate is less than the vertical distance between the light-emitting layer of the display light-emitting element and the first surface of the base substrate.
