An organic EL displaying apparatus which suppresses a defective display caused by a leak current at a time when an emission period controlling transistor is off is provided. The organic EL displaying apparatus comprises a plurality of pixels each of which includes an organic EL element, a power supply line, a driving transistor and the emission period controlling transistor, a data line, and a control line. In this apparatus, in a certain one of the pixels, a resistance Roff—ILM between source and drain electrodes of the emission period controlling transistor in an off state of the emission period controlling transistor, and a resistance Rbk—Dr between source and drain electrodes of the driving transistor in a state that a minimum gradation displaying data voltage has been applied to a gate electrode of the driving transistor satisfy Roff—ILM≧Rbk—Dr.
