Abstract
The invention provides a nanowire light emitting device and a manufacturing method thereof. In the light emitting device, first and second conductivity type clad layers are formed and an active layer is interposed therebetween. At least one of the first and second conductivity type clad layers and the active layer is a semiconductor nanowire layer obtained by preparing a layer of a mixture composed of a semiconductor nanowire and an organic binder and removing the organic binder therefrom.
