Abstract

Provided are a display substrate, a manufacturing method thereof and a display apparatus. The display substrate includes multiple sub-pixels, wherein each sub-pixel includes a light-emitting region and a non-light-emitting region, and each sub-pixel is provided with a drive circuit; the drive circuit includes a storage capacitor and multiple transistors; for each sub-pixel, the multiple transistors are in the non-light-emitting region, the storage capacitor is a transparent capacitor, and an orthographic projection of the storage capacitor on a base substrate coincides with the light-emitting region. A first electrode of the storage capacitor is disposed in a same layer as an active layer of the multiple transistors, but in a different layer from source and drain electrodes of the multiple transistors, and a second electrode of the storage capacitor is on a side of the first electrode close to the base substrate.
