A window structure for Gallium Nitride based Light Emitting Diode comprises: an Mg+ doped P window layer of a GaN compound; a thin semitransparent metal contact layer; an amorphous current spreading layer formed on the contact layer. The contact layer is formed of NiOx/Au; and the current spreading layer is formed of Indium Tin Oxide. The P electrode of the diode comprises a titanium adhesion layer which forms an ohmic connection with the current spreading layer and a Shottky diode connection with the Mg+ doped window layer.
