Abstract
The present invention provides a composite material in which an organic compound and an inorganic compound are composited, which is superior in conductivity, a composite material which is superior in a property of injecting carriers to an organic compound, and a composite material having low resistance with metal. Further, the present invention provides a light emitting element operating at a low drive voltage by applying the composite material to a current excitation type light emitting element, and a light emitting device consuming low power by manufacturing a light emitting device using the light emitting element. The present invention provides a composite material including metal oxide and an organic compound having an oxidation peak potential with respect to an oxidation-reduction potential of ferrocene in dimethylformamide (DMF) at room temperature within the range of 0 V and 1.5 V (vs. Fc/Fc+), preferably within the range of 0.1 V and 1.0 V (vs. Fc/Fc+).
