LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, AND ELECTRONIC APPLIANCE
摘要:
An object of the present invention is to provide a light-emitting element with high luminous efficiency, and a light-emitting element of low-voltage driving. Another object is to provide a light-emitting device with low power consumption by using the light-emitting element. Another object is to provide an electronic appliance with low power consumption by using the light-emitting device in a display portion. A light-emitting element includes, between a pair of electrodes, a layer containing a composite material of a first organic compound and an inorganic compound and a layer containing a second organic compound being in contact with the layer containing the composite material, wherein the second organic compound does not have a peak of an absorption spectrum in a wavelength region of 450 to 800 nm if the second organic compound is compounded with the inorganic compound.
