Abstract
A display substrate, manufacturing method thereof, and a display device. The display substrate includes a base substrate and a semiconductor layer and a conductive layer on the base substrate. The semiconductor layer includes a channel region and a doped region pattern of a transistor; the conductive layer includes a data line, and a first electrode and a second electrode of the transistor. An extension direction of an overlapping portion of the semiconductor layer with the data line is the same as an extension direction of the data line, and the semiconductor layer includes a first protrusion portion, and a size of an interval between an edge of the first protrusion portion away from the data line and the edge of the data line is greater than 0 and smaller than 3.0 microns.
