Abstract

Disclosed are a display substrate, a display device, a manufacturing method and a repairing method. A capacitor structure in the display substrate includes a first electrode and a second electrode. The first electrode includes a first main body portion extending in a first direction, first branch portions extending in a second direction, and a first connection portion connecting the first branch portions to the first main body portion. The second electrode includes a second main body portion extending in the first direction, second branch portions extending in the second direction, and a second connection portion connecting the second branch portions to the second main body portion. One side of the first electrode having the first branch portions faces one side of the second electrode having the second branch portions, and each first branch portion and a corresponding second branch portion form a capacitor.
