Abstract
Provided are a display substrate and a preparation method thereof, and a display apparatus. The display substrate includes a substrate, an active structure layer disposed on the substrate, a first source-drain structure layer disposed on a side of the active structure layer away from the substrate, and a second source-drain structure layer disposed on a side of the first source-drain structure layer away from the substrate. The active structure layer includes a first active layer and a second active layer. The first source-drain structure layer includes a first active via and a first source-drain electrode, and the first source-drain electrode is connected to the first active layer through the first active via; and the second source-drain structure layer includes a second active via and a second source-drain electrode, and the second source-drain electrode is connected to the second active layer through the second active via.
