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.
