Semiconductor light emitting device
A high external quantum efficiency is stably secured in a semiconductor light emitting device. At least one recess and/or protruding portion is created on the surface portion of a substrate for scattering or diffracting light generated in a light emitting region. The recess and/or protruding portion has a shape that prevents crystal defects from occurring in semiconductor layers.
