ABSTRACT:
The light-emitting element of the present invention includes a light-emitting layer and a layer for controlling movement of carriers between a pair of electrodes. The layer for controlling movement of carriers includes a first organic compound having a carrier transporting property and a second organic compound for reducing the carrier transporting property of the first organic compound, and the second organic compound is dispersed in the first organic compound. The layer for controlling movement of carriers is provided in such a manner, whereby change in carrier balance with time can be suppressed. Therefore, a light-emitting element having a long lifetime can be obtained.
