Abstract:
1. A group III nitride compound semiconductor light emitting device, comprising: a GaN substrate; a support substrate supporting the GaN substrate; a light emitting layer; a first conductive semiconductor layer formed between the GaN substrate and the light emitting layer; and a second conductive semiconductor layer formed at a side opposite to the first conductive semiconductor layer through the light emitting layer, wherein the GaN substrate has a thickness in a range of from 10 nm to 10 μm, wherein the first conductive semiconductor layer contains an InGaN layer, and wherein the InGaN layer includes an n-type InGaN layer, and the n-type InGaN layer has an In composition ratio X in a range of from 0.1 to 2% such that a radiant flux is 99% or more of a total radiant flux, the total radiant flux being 100% when the In composition ratio X in the InGaN layer is 0.8%.
