1. An array substrate, comprising:
a base substrate;
at least one adjusting portion on the base substrate, wherein the at least one adjusting portion has a first cross section in a plane perpendicular to the base substrate; the first cross section comprises a top side and a bottom side, and a first lateral side and a second lateral side; wherein the bottom side is closer to the base substrate than the top side, and an orthographic projection of the top side on the base substrate is within an orthographic projection of the bottom side on the base substrate; at least one of the first lateral side and the second lateral side is stepped;
a buffer layer on a side of the at least one adjusting portion away from the base substrate; and
a plurality of light-emitting devices on a side of the buffer layer away from the base substrate, wherein each of the plurality of light-emitting devices comprises a first electrode, a light-emitting layer and a second electrode which are sequentially arranged along a direction away from the base substrate; and an orthographic projection of a first electrode of each of at least some of the plurality of light-emitting devices on the base substrate at least covers an orthographic projection of a respective one of the at least one adjusting portion on the base substrate.
