In the Group III nitride-based compound semiconductor light-emitting device of the invention, an non-light-emitting area is formed in a light-emitting layer. In a light-emitting diode where light is extracted on the side of an n-layer, an outer wiring trace portion and an inner wiring trace portion of an n-contact electrode impedes light emission from the light-emitting layer. Therefore, there are provided, at the interface between a p-layer and a p-contact electrode, high-resistance faces having a width wider than the orthogonal projections of contact areas between the outer and inner wiring trace portions and the n-layer on the interface between the p-contact electrode and the p-layer. Through this configuration, current flow is limited, and portions having a total area equivalent to that of the high-resistance faces of the light-emitting layer serve as non-light-emitting areas. Thus, current can be supplied preferentially to an area of the light-emitting area where the outer wiring trace portion and the inner wiring trace portion are difficult to shade light, whereby light extraction efficiency with respect to supplied current can be enhanced.
