The light-emitting element includes: a light-emitting layer and a layer
for controlling the movement of carriers between a first electrode and a
second electrode. The layer for controlling the movement of carriers
contains a first organic compound and a second organic compound, and is
provided between the light-emitting layer and the second electrode. The
first organic compound has an electron transporting property, and the
second organic compound has an electron trapping property. The weight
percent of the first organic compound is higher than that of the second
organic compound. The light-emitting layer emits light when a voltage is
applied such that the potential of the first electrode is higher than
that of the second electrode. The first organic compound having the
electron transporting property may be replaced with an organic compound
having a hole transporting property, and the second organic compound
having the electron trapping property may be replaced with an organic
compound having a hole trapping property.
