Composite material, and light emitting element and light emitting device using the composite material
Abstract:
An object is to provide a light emitting element with low drive voltage which contains an organic compound and an inorganic compound. One feature of a light emitting element of the present invention is to include a layer containing a light emitting material between a pair of electrodes, in which the layer containing a light emitting material has a layer containing a carbazole derivative represented by General Formula (1) and an inorganic compound which exhibits an electron accepting property to the carbazole derivative represented by General Formula (1). With such a structure, the inorganic compound accepts electrons from the carbazole derivative, carriers are generated internally, and a drive voltage of the light emitting element can be reduced.
