Display substrate and display device

A display substrate comprising:

• a sub-pixel comprising a pixel circuit, and the pixel circuit comprises:
• a driving circuit, a data writing circuit, a first reset circuit, a first light emission control circuit, a second light emission control circuit, a light emitter element, a first light emission control line and a second light emission control line, wherein
• the driving circuit comprises a control terminal, a first terminal and a second terminal, and is configured to control a driving current flowing through the first terminal and the second terminal for driving the light emitter element to emit light;
• the data writing circuit is configured to write a data signal to the driving circuit in response to a scan signal;
• the first light emission control circuit is configured to apply a first voltage to the first terminal of the driving circuit in response to a first light emission control signal;
• the second light emission control circuit is configured to apply the driving current to the light emitter element in response to a second light emission control signal;
• the first reset circuit is configured to apply a first reset voltage to the control terminal of the driving circuit in response to a first reset signal, and the first reset signal and the first light emission control signal are simultaneously turn-on signals during at least a period of time;
• the first light emission control line and the second light emission control line respectively substantially extend along a first direction and are arranged in a second direction, and the second direction intersects with the first direction.
