A light-emitting element disclosed in the present invention includes a
light-emitting layer and a first layer between a first electrode and a
second electrode, in which the first layer is provided between the
light-emitting layer and the first electrode. The present invention is
characterized by the device structure in which the first layer comprising
a hole-transporting material is doped with a hole-blocking material or an
organic compound having a large dipole moment. This structure allows the
formation of a high performance light-emitting element with high luminous
efficiency and long lifetime. The device structure of the present
invention facilitates the control of the rate of the carrier transport,
and thus, leads to the formation of a light-emitting element with a
well-controlled carrier balance, which contributes to the excellent
characteristics of the light-emitting element of the present invention.
