Abstract
An illumination apparatus including a transparent substrate, an opposite substrate and an electroluminescence structure disposed between the transparent substrate and the opposite substrate is provided. The transparent substrate has a first region and a second region adjacent to the first region. The electroluminescence structure is disposed on the transparent substrate. The electroluminescence structure includes a first electrode disposed in the first region, an optical adjusting layer disposed in the second region, an organic electroluminescence layer disposed above the first electrode and the optical adjusting layer and a common electrode disposed above the organic electroluminescence layer. The optical adjusting layer is disposed between the organic electroluminescence layer and the transparent substrate.
