Abstract

A display panel includes: a base, a first electrode, a pixel definition layer and a first light-emitting functional layer. The first electrode is disposed on a side of the base; the pixel definition layer is disposed on the side of the base, and includes a first hollowed-out portion; the first hollowed-out portion includes a first opening and a second opening arranged oppositely, the first opening is closer to the base than the second opening, and the first opening exposes at least part of the first electrode; and the first light-emitting functional layer is disposed on sides of the pixel definition layer and the first electrode away from the base, and includes a second hollowed-out portion; an orthogonal projection of the second hollowed-out portion on the base is non-overlapping with an orthogonal projection of the first opening on the base.
