ABSTRACT:
A light-emitting element is provided which has a light-emitting layer between a first electrode and a second electrode, where the light-emitting layer has a first layer and a second layer; the first layer contains a first organic compound and a third organic compound; the second layer contains a second organic compound and the third organic compound; the first layer is provided to be in contact with the second layer on the first electrode side; the first organic compound is an organic compound with an electron transporting property; the second organic compound is an organic compound with a hole transporting property; the third organic compound has an electron trapping property; and light emission from the third organic compound can be obtained when voltage is applied to the first electrode and the second electrode so that the potential of the first electrode is higher than that of the second electrode.
