Abstract

An embodiment of the invention relates to a display substrate, a display panel and a manufacturing method thereof. The display substrate, the display panel and the manufacturing method thereof have the advantages that a sacrificial layer is arranged between a support substrate and a flexible panel, the part, corresponding to a bending area, of the sacrificial layer is carbonized through light treatment to form a viscosity reducing layer, a groove array is formed on the surface of one side, facing the bending area, of the viscosity reducing layer at the same time, and accordingly the bending stress of the bending area during bending can be reduced effectively, the bending area can be easily compressed by the aid of the groove array, and mechanical damage can be avoided effectively.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display substrate, a display panel and a manufacturing method thereof. Background technique [0002] The existing display substrate includes a supporting substrate and a flexible panel disposed on the supporting substrate. When bending, the part of the supporting substrate corresponding to the bending area of ​​the flexible panel needs to be evacuated. At present, the method of avoiding the space in the bending area of ​​the flexible panel is realized by attaching two sections of support material under the flexible panel. However, the spacing and fitting accuracy of the two supporting materials will lead to defects during bending, and the small bending radius of the bending area of ​​the flexible panel will easily cause the internal wiring to be damaged by stress and break, which will lead to the appearance of the flexible panel. bad.
