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: Disclosed are a display panel and a display device. The display panel includes a display region including a first display region and an optical component region, multiple pixel driver circuits and a light-shielding layer. The optical component region includes multiple light-emitting elements and multiple light-transmitting regions. The multiple pixel driver circuits are electrically connected to the multiple light-emitting elements; the multiple pixel driver circuits are connected to one another through multiple pixel drive signal lines, and at least one of the multiple pixel drive signal lines is a transparent wire. The light-shielding layer is provided with a light-shielding pattern, and a vertical projection of a region on a light-emitting surface is located within a vertical projection of the light-shielding pattern on the light-emitting surface, where non-transparent structures in the multiple pixel driver circuits and the multiple pixel drive signal lines are located in the region.
