[0061] Figure 8 A schematic structural diagram of the substrate is shown for the first embodiment of the present invention. Such as Figure 8 As shown, the display substrate in the embodiment of the present invention includes a display area 10 , a bending area 11 and a power supply area 12 , and the bending area 11 is located between the display area 10 and the power supply area 12 . A data signal line 13 is arranged on the bending area 11 , and the data signal line 13 connects the display area 10 and the power supply area 12 for transmitting signals. In the embodiment of the present invention, the display substrate bends the bending region 11 so that the data signal line 13 is located at the back of the display region 10 to reduce the frame of the display region 10 . In order to prevent the data signal line 13 from being broken due to bending, a groove is opened in the bending area 11, and then a flat layer is filled in the groove, so that the data signal line 13 is locate...

[0083] This embodiment shows that the preparation method of the substrate is basically the same as that of the aforementioned first embodiment. The difference from the aforementioned first embodiment is that after the formation of the first metal thin film layer, a For the passivation layer of the thin film layer, the passivation layer and the first metal thin film layer are respectively patterned by an etching process, and then etched to form the first groove and the second groove.

[0084] This embodiment has the technical effect of the aforementioned first embodiment, that is, it solves the problem that the short circuit of the data signal line is caused by the etching residue of the metal thin film layer due to the level difference of the groove.

Abstract

The embodiment of the present invention provides a display substrate, a method for manufacturing the same, and a display device. The method for manufacturing the display substrate includes: forming asubstrate including a display region and a bent region; forming an inorganic layer over the substrate; forming a source-drain layer over the inorganic layer in the display region; and forming a groovein the inorganic layer in the bent region. The method for manufacturing the display substrate can solve the residual metal thin film layer in the groove to avoid a short circuit between data signal lines.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] As the size of the display screen increases and the requirements for display performance increase, the existing single-layer source-drain layer sometimes cannot meet the demand, and it is necessary to introduce two-layer source-drain layers (hereinafter referred to as dual-source-drain layer products). The source and drain layers not only serve as the source and drain of the array substrate, but also serve as other electrical signals such as data signal lines and power lines of the display screen. Substrate bending technology has played a great role in today's display screens, bending the data signal lines to the back of the display screen, thereby greatly reducing the frame of the display screen. In existing dual-source-drain layer products, the first source-drain layer is us...
