Abstract

The invention provides a display substrate and a manufacturing method thereof, a display panel, and a display device; the display substrate comprises a substrate, a film transistor arranged on the first surface of the substrate, an electrode, and an insulation layer covering the electrode; the surface, far away from the electrode, of the insulation layer is provided with a groove; the orthographicprojection of the groove bottom wall on the substrate overlaps with the orthographic projection of the electrode on the substrate. The electrode of the display substrate is far away from the insulation layer, and the surface is flattened, thus allowing following formed each layer structure to have better flatness, further improving the tomography and fracture problems when the display substrate is bended.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to a display substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] Flexible display technology is an emerging technology developed in recent years, manifested as organic light emitting diode (OLED) display technology. Compared with traditional liquid crystal displays, OLED technology has good flexibility, and its process conditions can meet the needs of flexible substrates. With the vigorous development of flexible displays, a series of flexible materials have attracted people's attention. Representative ones are: organic materials, polythiophene materials, liquid metals, and carbon-based flexible materials. [0003] In the current liquid crystal display technology, the grid is usually formed by sputtering on one side of the substrate first, and then a gate insulating layer with unif...
