PROBLEM TO BE SOLVED: To obtain an organic light-emitting source for obtaining high efficiency with a desired luminous spectrum. SOLUTION: An organic electroluminescence device 205 comprises a substrate 208; a hole injection electrode arranged on the substrate; an anode buffer layer for covering the hole injection electrode; a polymer-based luminous layer for covering a hole-transporting layer; a small-molecule-based luminous layer 220 arranged on the polymer-based luminous layer; and an electron injection electrode arranged on the small-molecule-based luminous layer. Therefore, the organic electroluminescence device 205 can be used for a computer display, an information display, a television monitor, a telephone, a printer, and a display in a mark, lighting for white and colored light, lighting for houses, general area lighting, a backlight, and industrial lighting.
