<P>PROBLEM TO BE SOLVED: To provide a semiconductor light emitting device of what is called a side view type which has directional characteristics symmetrical in an angle-θ direction with respect to an optical axis as the center. <P>SOLUTION: The semiconductor light emitting device emits light mainly in a direction substantially parallel to a device mounting surface, and includes: a base substrate which is mounted with a semiconductor light emitting element on a main surface parallel to the device mounting surface and has a cutoff portion at a position where light emitted from the semiconductor light emitting element crosses the main surface defined forward of the semiconductor light emitting element in the light projection direction; and a first sealing resin 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 is emitted from a light emission surface through the cutoff portion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
