Zusammenfassung:Disclosed is an organic EL display device (10) that comprises a plurality of first electrode elements (32 1 ,32 2 ), a plurality of second electrode elements (34 1 , 34 2 ) crossing the first electrode elements (32 1 ,32 2 ), an organic light emitting layer sandwiched by the first electrode elements (32 1 ,32 2 ) and the second electrode elements (34 1 , 34 2 ), a first driving unit (20) passing light emitting current through the first electrode elements (32 1 ,32 2 ), and a second driving unit (40) that connects the second electrode elements (34 1 , 34 2 ) to ground to pass the light emitting current or to a second power supply (44) not to pass the light emitting current. The voltage of the second power supply is varied in synchronism with the voltage waveform of output of the light emitting current from the first driving unit.
