Abstract
The present invention provides a display substrate and a manufacturing method thereof and a display panel. The display substrate comprises a plurality of sub-substrates, distance measuring regions are provided on a base in space regions between the sub-substrates, the distance measuring region is configured to measure a distance between a mask plate and the base before forming each layer in the sub-substrates by using an exposure process, wherein a peripheral area of the distance measuring region is provided therein with a supporting layer on the base, the peripheral area is located in the space region and around the distance measuring region. There is no large segment difference between the peripheral area of the distance measuring region and the region, where the sub-substrate is located, of the display substrate, so that remarkable stress concentration cannot occur when the display substrate is subsequently aligned and assembled with other substrate.
