Abstract
A light emitting device includes: a substrate; a light emitting element disposed on the substrate; a wavelength conversion unit disposed on the substrate to cover at least an upper surface of the light emitting element; and a reflection unit formed to cover a side surface and a lower surface of the substrate and having a resin and a reflective filler dispersed in the resin. Light emitting devices having uniform characteristics can be obtained by minimizing a chromaticity distribution of white light with respect to the different light emitting devices.
