摘要： Disclosed are a display substrate, a manufacturing method thereof and a display apparatus. The display region (201) of the display substrate (20) includes an opening (201A), and a first display region (2011) and a second display region (2012) located at opposite sides of the opening (201A), and the peripheral region (202) includes an opening peripheral region (203) at least partially located in the opening (201A). The display substrate (20) further includes a first wire (2301) and a second wire (2302) arranged on a same layer; the first wire (2301) and the second wire (2302) pass through the first display region (2011), the opening peripheral region (203) and the second display region (2013), sequentially; in the opening peripheral region (203), the first wire (2301) includes a first bent portion (2311), the second wire (2302) includes a second bent portion (2312), and the first bent portion (2311) and the second bent portion (2312) are arranged side by side along the first direction (R1). The wiring manner of the display substrate (20) can reduce the arrangement space of the wiring and realize a narrow-frame design.

摘要： Provided are a display panel and a display device. An isolation dam is provided in a peripheral area of the display panel. The display panel includes: a display functional layer comprising a plurality of display signal traces; and a touch-control functional layer comprising a plurality of touch-control signal traces. On the binding side, there are a first boundary and a second boundary, and a first trace area located between the first boundary and the second boundary, the first boundary is closer to the display area than the second boundary. In the first trace area, the touch-control signal trace is arranged along a first direction and are led out from the binding circuit and connected to the touch-control pattern via the isolation dam and the first trace area in sequence, the display signal trace is arranged along a second direction and intersects with the touch signal trace. The display panel further comprises a signal shielding layer between the touch-control signal traces and the display signal traces in a direction perpendicular to the substrate, and an orthographic projection of the signal shielding layer onto the substrate at least partially covers the intersection area of the touch-control signal trace and the display signal trace within the first trace area. The display panel and display device can improve operational stability and reliability.
