Abstract

The invention discloses a display substrate, a manufacturing method thereof, and a display device, and belongs to the field of display technology. The display substrate includes: a base substrate, and a light-shielding layer arranged on the base substrate, the light-shielding layer is made of conductive material, and the part of the light-shielding layer located in the non-display area includes a first light-shielding pattern and a second light-shielding pattern arranged at intervals pattern; the side of the light-shielding layer away from the base substrate is provided with an intermediate insulating layer, and the part of the intermediate insulating layer located in the non-display area is provided with a first via hole and a second via hole; the side of the intermediate insulating layer away from the base substrate is provided with The metal layer, the part of the metal layer located in the non-display area includes a first power signal line and a second power signal line arranged at intervals, the first power signal line is connected to the first light-shielding pattern through the first via hole, and the second power signal line passes through The second via hole is connected with the second light-shielding pattern. The invention improves the display effect of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] In order to realize the narrow frame design of the display device, it is usually necessary to reduce the size of the non-display area of ​​the display substrate in the display device. [0003] In the related art, a plurality of power signal lines are arranged in the non-display area of ​​the display substrate, and the plurality of power signal lines can be used to provide power signals for the pixel units arranged in the display area. For example, the plurality of power signal lines may include: a VDD power signal line for providing a high level and a VSS power signal line for providing a low level. [0004] However, after the size of the non-display area of ​​the display substrate is reduced, the line width of the power signal line becomes narrower, resulting in an increase...
