1. An organic light-emitting display panel, comprising:
a substrate having an opening passing through the substrate;
a pixel array disposed on the substrate and comprising a plurality of pixels;
an isolation part disposed between the plurality of pixels and the opening and surrounding the opening,
wherein the isolation part comprises:
a first layer disposed on the substrate, wherein the first layer comprises a first portion and a second portion which are sequentially stacked in a direction away from the substrate, and an orthogonal projection of the first portion on the substrate falls within an orthogonal projection of the second portion on the substrate; and
a second layer disposed on a surface of the first layer away from the substrate,
a metal layer, the metal layer is disposed on two sides of the first portion of the first layer in a direction parallel to the substrate, and the metal layer and a first metal layer of the plurality of pixels are a same metal layer, wherein
the isolation part further comprises a protective layer disposed between the metal layer and the first layer, wherein the protective layer is in contact with a side of the second portion proximate to the substrate and the two sides of the first portion of the first layer in the direction parallel to the substrate, and a surface of the first portion facing the substrate, a surface of the protective layer facing the substrate, and a surface of the metal layer facing the substrate are aligned with one another in the direction parallel to the substrate; and
a light emitting material layer of the organic light-emitting display panel is broken at the isolation part.
