In a light emitting device, a P-type first region (506) and a P-type third region (508) are placed on both sides of an N-type second region (507) of a rod-like light emitting element (505). Therefore, even if connection of the first, third regions (506, 508) of the rod-like light emitting element (505) relative to the first, third electrodes (1, 3) is reversed, a diode polarity relative to the first, third electrodes (501, 503) is not reversed, making it possible to effectuate normal light emission. Thus, a connection of the first, third regions (506, 508) relative to the first, third electrodes (501, 503) may be reversed during a manufacturing process, making it unnecessary to provide marks or configurations for discrimination of orientation of the rod-like light emitting element (505), so that the manufacturing process can be simplified and manufacturing cost can be cut down.
