Abstract:
A light emitting apparatus includes a pixel circuit and a driving circuit which drives the pixel circuit. The pixel circuit includes: a driving transistor which generates a driving current; a light emitting device that determines gradation depending on the driving current; a light emission control transistor; a discharge transistor; a capacitor device; and a first switching device interposed between a gate and a drain of the driving transistor.
