Abstract:
1. A pixel circuit comprising: a first organic electroluminescence element which contributes to light emission; a second organic electroluminescence element which does not contribute to light emission; a storage capacitor to which data is written including a black level; a second driving transistor which supplies a drive current corresponding to data written to the storage capacitor to the second organic electroluminescence element; a first driving transistor which supplies, to the first organic electroluminescence element drive current which corresponds to a drive voltage that reflects brightness degradation or current degradation in the second organic electroluminescence element, the second driving transistor supplying a predetermined drive current to the second organic electroluminescence element including data of the black level; and means for setting the drive voltage of the first driving transistor to a voltage reflecting the brightness degradation or current degradation in the second organic electroluminescence element, wherein: wherein:
