摘要： A semiconductor light emitting device includes a substrate formed of a first material; and a convex portion protruding from the substrate and including: a first layer formed of the first material as that of the substrate; and a second layer formed of a second material different from the first material and disposed on the first layer. A second height of the second layer is greater than a first height of the first layer.
