A lighting apparatus includes a first organic electroluminescence device. The first organic electroluminescence device has a substrate, a first organic electroluminescence element, which is formed on the substrate, and a light emitting portion. At least one second organic electroluminescence device is stacked on the light emitting portion. The second organic electroluminescence device has a transparent substrate and a transparent second organic electroluminescence element, which is formed on the transparent substrate. Therefore, the lighting apparatus can freely set the illumination intensity. |
