Abstract
A method for driving an organic electroluminescent element including a first light-emitting layer and a second light-emitting layer comprises: applying a second current peak value to the second light-emitting layer exhibits a lower luminous efficiency than the first light-emitting layer at a current density of the second current peak value; and applying a first current peak value to the first light-emitting layer, wherein the first current peak value has a higher current density than the second current peak value.
