Abstract
A display substrate is provided, including: a base substrate and a plurality of sub-pixels disposed on the base substrate. Each sub-pixel includes a pixel driving circuit, and the pixel driving circuit includes a writing transistor, a compensation transistor, a first reset transistor, and a storage capacitor. The display substrate includes a semiconductor layer, a first conductive layer and a second conductive layer disposed in sequence on the base substrate. Gates of the writing transistor, the compensation transistor and the first reset transistor are in the first conductive layer and are implemented as an integral structure. Active layers of the writing transistor, the compensation transistor and the first reset transistor are in the semiconductor layer. A first storage capacitor electrode of the storage capacitor is in the first conductive layer, and a second storage capacitor electrode of the storage capacitor is in the second conductive layer.
