Abstract: A subpixel circuit and a display device including the subpixel circuit are discussed. The subpixel circuit in one example includes a light emitting element configured to receive a high-potential driving voltage at an anode electrode, and a driving transistor including a first node, a second node, and a third node. The subpixel circuit further includes a scan transistor controlled by a first scan signal and transmitting a data voltage through a data line, a storage capacitor, and a control circuit configured to control operations of the driving transistor, the scan transistor, and the storage capacitor. The control circuit can be located between a cathode electrode of the light emitting element and a low-potential base voltage line.
