Abstract:
1. A semiconductor light emitting device of gallium nitride compound comprising: a substrate, an n-type component composed of GaN or a material mainly made of GaN, disposed on said substrate directly or by way of other layer, an undoped luminous part disposed directly or by way of other layer at the opposite side of the substrate side in said n-type component, a p-type component disposed directly or by way of other layer at the opposite side of the n-type component side in said luminous part, and electrodes disposed in said p-type component and n-type component individually, wherein said n-type component has a first region and a second region in a thickness direction, said first region and second region are disposed sequentially from the substrate side, the second region and substrate do not contact with each other, the first region and second region are disposed directly or by way of other layer, the second region is set at a higher carrier concentration than the first region, and its carrier concentration is 2×10
