Abstract
A semiconductor light emitting device able to emit a high intensity, stable light. An edge surface lighting type light emitting diode array is formed on a substrate. A light emitting edge surface of each light emitting element is formed by an etching method. A surface of the substrate in front of the light emitting edge surface is formed in multiple stage so that a light beam is not reflected by the surface of the substrate.
