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.
