ABSTRACT:
A pixel circuit including a storage capacitor to which data is written including a black level; a second driving transistor supplies a drive current corresponding to data written to the storage capacitor to a second organic electroluminescence element; a first driving transistor supplies to a first organic electroluminescence element drive current that reflects brightness degradation or current degradation in the second organic electroluminescence element, wherein the second driving transistor supplies a predetermined drive current to the second organic electroluminescence element including data of the black level; and the drive voltage of the first driving transistor is set to a voltage reflecting the brightness degradation or current degradation in the second organic electroluminescence element.
