Title:
DISPLAY SUBSTRATE, DISPLAY DEVICE, AND DISPLAY SUBSTRATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/037324
Kind Code:
A9
Abstract:
The present disclosure relates to the technical field of display, and provides a display substrate, a display device, and a display substrate manufacturing method, capable of solving the problem of short circuits between adjacent metal wires in existing display substrates. The display substrate of the present disclosure comprises a display area and a peripheral area surrounding the display area. The display substrate comprises: a substrate, a first conductive layer and a second conductive layer which are located on the substrate and are sequentially arranged in the direction away from the substrate, and a first organic insulating layer located between the first conductive layer and the second conductive layer. The first conductive layer comprises a plurality of first metal wires extending in a first direction. The second conductive layer comprises a plurality of second metal wires extending in the first direction. In the peripheral area, the first organic insulating layer is divided, and the edge of the first organic insulating layer extends in a second direction and forms a first step. The second direction intersects with the first direction. The first step comprises at least one protruding structure and at least one recess structure which are located between the adjacent second metal wires.
