Abstract: A display panel and a display apparatus are provided. The display panel includes pixel circuits in a display region, a light-emitting device, and signal lines. The pixel circuits are electrically connected to the light-emitting devices, and the signal lines are electrically connected to the pixel circuits. The signal lines include constant voltage signal lines extending in a first direction and connected to a constant voltage terminal. The display region includes a first display region and a second display region. The constant voltage signal lines include first constant voltage signal lines located in the first display region and second constant voltage signal lines located in the second display region. A distance between two adjacent first constant voltage signal lines in the first display region is D1, and a distance between two adjacent second constant voltage signal lines in the second display region is D2, where D1≥D2.

Abstract: Provided are a display panel and a display device. The display panel includes a first display region and a second display region. The display panel further includes a pixel circuit, and the pixel circuit is configured to drive a light-emitting element to emit light. The distribution density of the pixel circuit in the first display region is less than the distribution density of the pixel circuit in the second display region. The first display region includes a compensation structure, and the compensation structure includes at least one layer of compensation film. The first display region further includes multiple first light-emitting elements, and the multiple first light-emitting elements each includes an anode. The anode at least partially overlaps the compensation structure in the first direction, and the first direction is perpendicular to a plane in which a substrate is located.
