Abstract: The present disclosure provides a display substrate and a display device, and belongs to the field of display technology. The display substrate provided by the present disclosure has a display area and a peripheral area surrounding the display area, and includes a substrate; a plurality of pixel circuits on the substrate and in the display area; and a plurality of dummy pixel circuits on the substrate and in the peripheral area; wherein the number of transistors in each dummy pixel circuit is smaller than the number of transistors in each pixel circuit. Because the number of the transistors in the dummy pixel circuit is smaller than the number of the transistors in the pixel circuit, space occupied by the dummy pixel circuit in the peripheral area can be reduced, thereby facilitating realization of a display device with a narrow bezel.
