Claim 14:
15. The electroluminescent display substrate of claim 1, wherein the encapsulation structure comprises:
a first inorganic encapsulation layer arranged on a side of the display light-emitting element away from the base substrate;
an organic encapsulation layer arranged on a side of the first inorganic encapsulation layer away from the base substrate; and
a second inorganic encapsulation layer arranged on a side of the organic encapsulation layer away from the base substrate,
wherein an orthographic projection of the organic encapsulation layer on the base substrate has an area less than an area of an orthographic projection of each of the first inorganic encapsulation layer and the second inorganic encapsulation layer on the base substrate, and
wherein an orthographic projection of the first light-shielding portion on the base substrate overlaps the orthographic projection of the organic encapsulation layer on the base substrate, and an orthographic projection of the second light-shielding portion on the base substrate does not overlap the orthographic projection of the organic encapsulation layer on the base substrate.
