1. A display panel, comprising:
a substrate; and
a circuit layer located at a side of the substrate and comprising a light-emitting shift circuit; and
a top light-shielding layer configured to receive a voltage signal,
wherein the light-emitting shift circuit comprises:
a first output module, wherein the first output module is electrically connected to a first node, a first fixed potential signal line, and a light-emitting control signal line, and is configured to, in response to a voltage of the first node, transmit a light-emitting enable voltage provided by the first fixed potential signal line to the light-emitting control signal line; and
at least one control module electrically connected to the first node and comprising at least one control transistor;
wherein the top light-shielding layer is located at a side of the at least one control transistor facing away from the substrate, and, in a direction perpendicular to a plane of the substrate, the top light-shielding layer overlaps with a channel of one or more of the at least one control transistor,
wherein the top light-shielding layer is arranged at one side of the channel adjacent to a light-exiting side of the display panel.
