Abstract:
The present invention discloses a thin-film light-emitting device including a charge generating junction layer and a method of fabricating the thin-film light-emitting device. The thin-film light-emitting device including a charge generating junction layer according to one embodiment of the present invention includes a negative electrode; at least one light-emitting unit formed on the negative electrode and including a charge generating junction layer, an electron injection/transport layer, a thin-film light-emitting layer, and a hole injection/transport layer in a sequential order; and a negative electrode formed on the light-emitting unit. In the thin-film light-emitting device of the present invention, the charge generating junction layer has a layer-by-layer structure in which a p-type semiconductor layer and an n-type semiconductor layer are formed, and the concentration of oxygen vacancies at the interface between the p-type and n-type semiconductor layers is adjusted by annealing the n-type semiconductor layer.
