Abstract
A display substrate and a display device are provided. The display substrate includes a first display region including first light emitting unit groups and first pixel circuit groups connected with the first light emitting unit groups, a second display region including second light emitting unit groups, second pixel circuit groups connected with the second light emitting unit groups and third pixel circuit groups, and a third display region including third light emitting unit groups connected with the third pixel circuit groups. Each light emitting unit group includes light emitting units of different colors. The light emitting unit includes a main body electrode, an area of the main body electrode of at least one color light emitting unit in a non-edge region of the second display region is greater than that of a main body electrode of the same color light emitting unit in the first display region.
