Abstract
An organic light emitting diode display substrate, comprises: a base substrate, and a first data line, a driving thin film transistor and an energy storage capacitor which are disposed on the base substrate, wherein the energy storage capacitor comprises a first capacitor plate and a second capacitor plate disposed opposite to each other, and the second capacitor plate is electrically connected to a gate of the driving thin film transistor, in a direction away from the base substrate, the first capacitor plate is disposed between the first data line and the second capacitor plate, wherein the display substrate further comprises a first shielding portion, which is electrically connected to the first capacitor plate and is disposed at least partially between the second capacitor plate and the first data line. A method of manufacturing the display substrate and a display device are further provided.
