A display substrate includes a base substrate, touch electrodes, and signal lines. At least some of the signal lines are electrically connected to the touch electrodes. The signal line includes a first signal line and a second signal line adjacent to each other. The first signal line and the second signal line respectively comprise a first-layer wiring and/or a second-layer wiring overlapped with each other in a direction perpendicular to the base substrate and electrically connected to each other. A line width of the first signal line is greater than a line width of the second signal line. The first-layer wiring of at least one of the first signal line or the second signal line is disconnected, and the second-layer wiring of the first signal line is continuous in a disconnected position.
