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.

Display substrate with uniform gate insulation structure

The present invention provides a backplane structure and a display device including the backplane structure. The backplane structure includes a backplate, a plurality of support components provided on a side of the backplate, and a control unit, wherein each of the support components includes a signal receiving element and an executive element, the signal receiving element may receive a control signal sent by the control unit, and the executive element has one end fastened to the backplate and is capable of being contracted or extended when the control signal is received by the signal receiving element. The display device provided by the present invention can not only achieve flat display, but also achieve curved display with different curvatures.
