Abstract
A light emitting device includes: a substrate having opposed first and second main faces; a light emitting element mounted on the first main face of the substrate; and a driver integrated circuit (IC) formed in an area corresponding to a lower side of the light emitting element within the substrate, and adjusting the amount of current applied to the light emitting element. Since the circuit provided to drive a light emitting diode (LED) is integrated within the substrate, a compact light emitting device having an integrated structure can be obtained.
