Electrode for semiconductor light emitting device

An object of the present invention is to provide an electrode that can produce powerful light emission with low driving voltage, without reducing crystallinity. The electrode for a semiconductor light emitting device has a structure with an n-type or p-type electrode and an opposing p-type or n-type electrode on the same side of the light emitting device. Both electrodes comprise a bonding pad and a transparent conductive layer. Preferably, the light emitting device is a GaN-based semiconductor light emitting device. The material of the transparent conductive layer is a metal oxide such as ITO, or a metal such as Al, Ni.
