Abstract
The present disclosure provides a display substrate, a manufacturing method thereof and a display apparatus, and relates to the field of display technology. The manufacturing method of a display substrate includes providing a base substrate, and forming pixels on the base substrate, wherein the forming pixels includes: forming a first auxiliary electrode on the base substrate; forming a first interlayer insulating layer on a side of the first auxiliary electrode away from the base substrate; sequentially forming a second conductive film and a first photoresist layer, exposing the first photoresist layer with a mask plate having regions of different light transmittances by controlling exposure time based on requirements on an operating frequency band of the pixels, to form a source electrode and a drain electrode of the thin film transistor and a second auxiliary electrode, forming a second interlayer insulating layer; and forming a pixel electrode.
