    Abstract: A display substrate and a manufacturing method thereof, and a display panel are provided. The display substrate includes at least one set of signal lines and at least one shielding structure disposed on a base substrate. The shielding structure is electrically connected to a DC power source. The shielding structure includes a shielding portion. Each set of signal lines includes a first signal line and a second signal line at different layers. Orthographic projections of first signal line and second signal line on base substrate overlap and have an overlapping region. Shielding portion is located between the first signal line and the second signal line, and insulated from the two signal lines. An orthographic projection of the shielding portion on base substrate at least partially overlaps the overlapping region. Since voltage on shielding structures is stable, thereby effectively avoiding crosstalk between the two signal lines in set of signal lines.
