Patent ID: 7956828

Claim:
An organic electroluminescence display device, comprising: an organic electroluminescence element having a structure wherein an organic luminescent medium comprising a host compound and a phosphorescent luminous compound, is sandwiched between a top electrode and a bottom electrode; and a driving circuit to drive the organic electroluminescence element, the circuit comprising a thin film transistor for controlling the luminescence of the organic electroluminescence element, wherein the driving circuit is for applying between the electrodes of the organic electroluminescence element, a pulse wave having an electric pulse voltage (V 1 ) to cause the organic luminescent medium to emit luminescence, and subsequently applying a voltage (V 2 ) in the direction reverse to that of voltage (V 1 ); wherein the absolute value of the reverse voltage (V 2 ) is smaller than voltage (V 1 ); and wherein the absolute value of the reverse voltage (V 2 ) is set to 5% to 80% of voltage (V 1 ).
