Abstract
Provided are a display substrate, a preparation method thereof and a display apparatus. The display substrate includes a first semi-conductive layer, a first conductive layer, a second conductive layer, a second semi-conductive layer, a third conductive layer, an interlayer insulating layer and an organic layer stacked on a substrate. The first semi-conductive layer includes an active layer of a polysilicon transistor, the first conductive layer includes a gate electrode of a polysilicon transistor and a first electrode plate of a storage capacitor, the second conductive layer includes a second electrode plate of a storage capacitor, the second semi-conductive layer includes an active layer of an oxide transistor, and the third conductive layer includes a gate electrode of an oxide transistor.
