Abstract
A display substrate, a manufacturing method thereof and a display device are provided. The display substrate includes: a base substrate, a display region disposed on the base substrate, and a peripheral region disposed at a periphery of the display region, and the peripheral region is provided with a filling area recessed toward the base substrate; the filling area is provided with an alignment mark and a filling material; and the filling material is configured for filling the filling area. The filling material is provided in filling the filling area of the display substrate, to reduce or eliminate a segment difference at the filling area, and further to avoid the incorrect alignment of liquid crystal molecules caused by the segment difference in the rubbing process, and finally to avoid poor display due to uneven display of a display panel in the working process.
