Abstract
A display substrate, a method of manufacturing the display substrate, and a display device are provided. The display substrate includes: a base substrate, a plurality of sub-pixels, a gate driving circuit, a plurality of input contact pads, a plurality of output contact pads and a contact pad insulating layer. Surfaces of the input contact pads away from the base substrate and surfaces of the output contact pads away from the base substrate are exposed from the contact pad insulating layer. The contact pad insulating layer includes a first portion having a first thickness and a second portion having a second thickness smaller than the first thickness. Edges of the input contact pads and edges of the output contact pads are covered by the first portion. The second portion is located in the region between the input contact pads and the output contact pads.
