Abstract
The present disclosure provides a display substrate, a manufacturing method thereof, a display panel, and a display device. The display substrate includes: a substrate; and a thin film transistor, provided on a first surface of the substrate and including an electrode and an insulating layer, the insulating layer covering the electrode, wherein a groove is formed on a surface of the insulating layer away from the electrode, and an orthogonal projection of a bottom wall of the groove on the substrate overlaps with an orthogonal projection of the electrode on the substrate. In the display substrate provided by the present disclosure, a surface of the insulating layer covering the electrode away from the substrate is planarized, so that the subsequently formed layer structures may have better flatness, and problems of faulting, fracturing and so on likely occurring when the display substrate is bent may be solved.
