Display substrate including heat dissipation hole structure and display device

A display substrate, comprising:

• a base substrate, and a gate driving circuit and a plurality of sub-pixels arranged on the base substrate;
• wherein the display substrate further comprises a heat dissipation hole structure, and at least part of an orthographic projection of the heat dissipation hole structure onto the base substrate is located between an orthographic projection of the gate driving circuit onto the base substrate and an orthographic projection of the sub-pixels onto the base substrate,
• wherein the gate driving circuit comprises a first output transistor and a first capacitor, a first plate of the first capacitor is coupled to a gate electrode of the first output transistor, and a second plate of the first capacitor is coupled to a second electrode of the first output transistor;
• the heat dissipation hole structure comprises a plurality of sixth heat dissipation holes, and the sixth heat dissipation hole penetrates through the first plate and the second plate.
