Abstract
The present disclosure provides a display substrate and a manufacturing method thereof, and a display apparatus. The display substrate has a fingerprint identification region. The display substrate includes a base substrate; a display unit on the base substrate and including a display thin film transistor and a light-emitting device, a second electrode of the display thin film transistor being coupled to a first electrode of the light-emitting device; and a fingerprint identification unit at a gap between adjacent display units in the fingerprint identification region and including a fingerprint identification transistor and a photosensitive device, a first electrode of the fingerprint identification transistor being coupled to a second electrode of the photosensitive device. The display substrate further includes a gate insulating layer on a side of an active layer of the display thin film transistor and an active layer of the fingerprint identification transistor distal to the base substrate.
