    Abstract: A light emitting device package includes a package substrate and a submount on the package substrate. An upper surface of the submount includes a central region, first and second base regions spaced from the package substrate, relative to the central region, and a sloped region between the central region and the first and second base regions. A light emitting device chip is in the central region. A first electrode layer is between the central region and the light emitting device chip and extends onto the sloped region and the first base region. A second electrode layer is between the central region and the light emitting device chip, extends onto the sloped region and the second base region, and is spaced apart from the first electrode layer. First and second reflective layers are on the first and second electrode layers, respectively, and overlap the sloped region.
