摘要： 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.

摘要： A display panel and a display apparatus are described. In an embodiment, the display panel includes a display area and a bezel area; a first support structure located in the display area, the first support structure including a plurality of first support portions; an encapsulation adhesive located in the bezel area; a second support structure located in the bezel area. In an embodiment, at different positions of the bezel area, the second support structure and the encapsulation adhesive are at an equal distance from each other within a preset error range; the second support structure includes at least one second support portion; and in a direction perpendicular to a plane in which the display panel is located, at least some of the second support portions each has orthographic projection area larger than orthographic projection area of the first support portion.
