Abstract
An organic light emitting element includes a first electrode, a second electrode, and an organic layer. The organic layer includes a first emission layer between the first electrode and the second electrode, a second emission layer between the first emission layer and the second electrode, and an electron injection layer (EIL) between the first emission layer and the second emission layer, the electron injection layer (EIL) containing fullerene (C60).
