Zusammenfassung:A pixel may include a light emitting element; a data write transistor that writes a data voltage; a driving transistor that applies a driving current to the light emitting element based on the data voltage; a hold capacitor including a first electrode to which a first power supply voltage is applied, and a second electrode electrically connected to a first node; a storage capacitor including a first electrode electrically connected to the first node, and a second electrode electrically connected to a control electrode of the driving transistor; at least one polysilicon thin film transistor; and at least one oxide thin film transistor. The at least one oxide thin film transistor may be disposed between the at least one polysilicon thin film transistor and the hold capacitor, or between the at least one polysilicon thin film transistor and the storage capacitor.
