Embodiment 1

[0036] This embodiment provides a display substrate, including a base 10, a first insulating layer 20 disposed on the base 10, a first signal line 31 disposed on the side of the first insulating layer 20 away from the base 10, and a cover covering the first signal line 31. The second insulating layer 40, the second signal line 32 disposed on the side of the second insulating layer 40 away from the substrate 10, the first signal line 31 and the second signal line 32 have an overlapping area.

[0037] For example figure 1 with figure 2 As shown, the second insulating layer 40 separates the first signal line 31 and the second signal line 32 , and the two have an overlapping area.

[0038] A groove is provided on the first insulating layer 20 , and the first signal line 31 is disposed in the groove at least at the overlapping area.

[0039] In one embodiment, at least part of side surfaces of the first signal line 31 located in the groove are in contact with the wall of the gro...

Embodiment 2

[0063] This embodiment provides a method for manufacturing a display substrate. The display substrate is the display substrate provided in Embodiment 1. The manufacturing method includes:

[0064] forming a first insulating layer 20 on the substrate 10 through a patterning process, and forming grooves in the first insulating layer 20;

[0065] forming a first signal line 31 on the first insulating layer 20 through a patterning process;

[0066] forming a second insulating layer 40 on the first signal line 31;

[0067] The second signal line 32 is formed on the second insulating layer 40 through a patterning process.

[0068] That is, the first insulating layer 20 , the first signal line 31 , the second insulating layer 40 , and the second signal line 32 in Embodiment 1 are sequentially formed on the substrate 10 .

[0069] Optionally, when the first insulating layer 20 is formed using a silicone glass solution, forming the first insulating layer 20 on the substrate 10 throug...

Embodiment 3

[0095] This embodiment provides a display device, including the display substrate provided in Embodiment 1 of the present invention.

[0096] Specifically, the display device can be any product with a display function such as a liquid crystal display panel, an organic light-emitting diode (OLED) display panel, an electronic paper, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, a navigator, or the like. part.

Abstract

The invention provides a display substrate, a manufacturing method thereof, and a display device, belongs to the technical field of displaying and at least partially solve the problem that an existingdisplay substrate experiences wire breaking and poor ESD (electro-static discharge). The display substrate includes a base, a first insulating layer arranged on the base, a first signal wire arrangedon the side of the first insulating layer far away from the base, a second insulating layer covering the first signal wire, and a second signal wire arranged on the side of the second insulating layer far away from the base; the first signal wire and the second signal wire overlap; the first insulating layer is provided with a trench; at least the overlay part of the first signal wire is arrangedin the trench.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a method for manufacturing the display substrate, and a display device. Background technique [0002] In an existing display substrate (such as a liquid crystal display substrate or an OLED display substrate), in order to supply power to each pixel, the display substrate is provided with cross-arranged gate lines and data lines. There is insulation. [0003] In order to reduce the resistance of the gate line, the cross-sectional area of ​​the gate line must be large enough. Because of its limited width, its thickness is increased, which leads to high and steep side walls of the gate line. When the gate line is below the data line, the gate line The insulating layer at the sidewall is relatively thin, and the data line at the sidewall of the gate line is also relatively thin. A thinner insulating layer can easily lead to poor ESD, and a thinner ...
