Abstract
A display substrate and a manufacturing method thereof, and a display panel are provided. The display substrate includes a base substrate with a black matrix BM disposed thereon. The base substrate is provided with a display area and a non-display area, and the BM disposed in the non-display area comprises a first BM portion and a second BM portion. The first BM portion and the second BM portion are sequentially arranged in a direction away from the center of the base substrate, and a gap exists between the first BM portion and the second BM portion. When an external electric field exists around the display substrate, the second BM portion can effectively shield the external electric field, thereby effectively preventing the external electric field from affecting the display area of the display panel. Thus, the display effect of the display substrate is improved.
