Abstract
A display substrate, a display panel and a display apparatus are provided. The display substrate includes a base substrate, a first display region, and a second display region, and a light transmittance of the first display region is greater than that of the second display region A plurality of sub-pixels are arranged on the base substrate and in the first display region, wherein the sub-pixels include a first pixel driving circuit and a first light-emitting device, and the first pixel driving circuit includes a compensation transistor, a switching transistor, and a light-emitting device initialization transistor each having an active layer. A scan signal line is provided in the first display region. An orthographic projection of the scan signal line on the base substrate overlaps with that of the active layer of each of the compensation transistor, the switching transistor and the light-emitting device initialization transistor on the base substrate.
