Abstract: Provided are a display substrate and a preparation method thereof, a display panel, and a display device. The display substrate includes a substrate and a plurality of pixel units on the substrate. The pixel unit comprises a plurality of functional layers that are sequentially arranged in a direction away from the substrate. At least one of the plurality of functional layers, which is close to the substrate, constitutes a vertical thin film transistor (VTFT). At least one of the plurality of functional layers, which is away from the substrate, constitutes an organic light-emitting transistor (OLET). An orthographic projection region of the OLET on the substrate and an orthographic projection region of the VTFT on the substrate at least partially overlap.
