Display substrate, manufacturing method and display device

A display substrate, comprising a driving circuit arranged on a base substrate, wherein the driving circuit includes a first node control circuit, and the first node control circuit is configured to control a potential of a first node;

• the first node control circuit includes a first transistor and a second transistor;
• a gate electrode of the first transistor is electrically connected to a first control terminal, and a second electrode of the first transistor is electrically connected to the first node;
• a gate electrode of the second transistor is electrically connected to a second control terminal, a first electrode of the second transistor is electrically connected to the first node, and a second electrode of the second transistor is electrically connected to a second voltage terminal;
• the display substrate further includes a first connection structure and a second connection structure arranged on the base substrate;
• the first transistor is connected to a part of the first connection structure;
• and/or, the second transistor is connected to a part of the second connection structure,
• wherein the first connection structure includes a first connection portion and a second connection portion, the first connection portion and the second connection portion are arranged in different layers;
• wherein the display substrate further includes a first conductive layer, the first connection portion is electrically connected to the second connection portion through the first conductive layer and a first via hole.
