Abstract
A display substrate and a display device. The display substrate includes a pixel circuit in which the driving circuit controls a driving current for driving the light emitter element to emit light; the first light emission control circuit applies a first voltage to a first terminal of the driving circuit in response to a first light emission control signal; the second light emission control circuit applies the driving current to the light emitter element in response to a second light emission control signal; the first reset circuit applies a first reset voltage to the control terminal of the driving circuit in response to a first reset signal; the first reset signal and the first light emission control signal are simultaneously turn-on signals during a period; the first light emission control line and the second light emission control line extend along a first direction and are arranged in a second direction.
