The inventive concept provides light emitting devices and methods of manufacturing a light emitting device. The light emitting device may include a transparent substrate including a first region and a second region, a first transparent electrode disposed on a first surface of the transparent substrate, a second transparent electrode facing and spaced apart from the first transparent electrode, an organic light emitting layer disposed between the first and second transparent electrodes, an assistant electrode disposed between the first and second transparent electrodes and selectively masking the second region, and a light path changing structure disposed on a second surface of the transparent substrate and selectively masking the second region.
