Abstract
A display substrate and a manufacturing method thereof, and a display device are provided. The display substrate has a display region and an electrode opening region, the display region includes a first electrode layer and a spacer layer on a base substrate; the electrode opening region includes a third electrode layer and a spaced insulating layer on the base substrate, the third electrode layer includes a plurality of electrode openings, the spaced insulating layer includes a plurality of insulating patterns, each insulating pattern fills a corresponding electrode opening; a maximum distance between a side of the spaced insulating layer away from the base substrate and the base substrate is a first distance, a maximum distance between a side of the spacer layer away from the base substrate and the base substrate is a second distance, a ratio of the first distance to the second distance ranges from 0.9 to 1.1.
