Abstract: A display panel and a display device, including a substrate, a circuit layer located at a side of the substrate, and a top light-shielding layer configured to receive a voltage signal. The circuit layer includes a light-emitting shift circuit, including a first output module and a control module. 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. The control module is connected to the first node and includes a control transistor. The top light-shielding layer is located at a side of the control transistor. In a direction perpendicular to the substrate, the top light-shielding layer overlaps with a channel of the control transistor.

Abstract: An array substrate, a display panel and a display device are provided. The array substrate includes: a substrate, a pixel circuit arranged on one side of the substrate and a body part. The pixel circuit includes a driving transistor and a threshold compensation transistor, a first electrode of the threshold compensation transistor is connected to a gate of the driving transistor, and a second electrode of the threshold compensation transistor and a first electrode of the driving transistor are both connected to a connection part. The body part is electrically connected to a power supply voltage signal end. An orthographic projection of the connection part on the substrate at least partially overlaps with an orthographic projection of the body part on the substrate.
