摘要： Provided is a display substrate and a display device, and relates to the field of display technologies. In the display substrate, because at least two pixels disposed on the base substrate may share the same light emitting control circuit connected to the light emitting control lines, the number of light emitting control circuits required to be set in the display substrate may be reduced, or the number of light emitting control lines required to be set in the display substrate may be reduced. That is, the area, occupied by each pixel, of the base substrate is smaller. Therefore, both the gate drive circuit that provides the signal for the signal line connected to the pixel, and the drive signal connected to the gate drive circuit can be disposed on the base substrate. The display substrate provided in the present disclosure has a higher resolution.
