摘要： One object of the present invention is to provide a light emitting element that includes an organic compound and an inorganic compound and has low driving voltage. The light emitting element of the invention includes a plurality of layers between a pair of electrodes, wherein the plurality of layers includes a layer that contains a carbazole derivative represented by a general formula (1) and an inorganic compound exhibiting an electron accepting property with respect to the carbazole derivative. By utilizing this structure, electrons are transported between the carbazole derivative and the inorganic compound and carriers are internally generated, and hence, the driving voltage of the light emitting element can be reduced.
