Abstract
A semiconductor light emitting device of what is called a side view type can achieve directional characteristics having substantial symmetry with respect to an optical axis. The semiconductor light emitting device can emit light in a direction substantially parallel to a surface on which the semiconductor light emitting device is to be held. The semiconductor light emitting device can include a semiconductor light emitting element emitting light in a light emitting direction parallel to the surface on which the semiconductor light emitting element is to be held, a base substrate having a main surface on which the semiconductor light emitting device is held, the main surface being parallel to the surface on which the semiconductor light emitting device is to be held. The base substrate can have a cutoff portion defined forward of the semiconductor light emitting element in the light emitting direction and in a position in which light emitted from the semiconductor light emitting element crosses the main surface. A light-transmitting first sealing resin can be provided on the base substrate, to bury the semiconductor light emitting element while filling the cutoff portion. The light emitted from the semiconductor light emitting element can travel through the cutoff portion.
