  • Patent number: 9041283
    Abstract: A light-emitting device package is provided including: a package substrate and a light-emitting device mounted on the package substrate. The package substrate includes first and second conductive regions each having a portion overlapping the light-emitting device. An electrode separator extends across the package substrate while penetrating the package substrate between the first and second conductive regions to electrically separate the first and second conductive regions from each other. A stress release portion surrounds at least a portion of each of the first and second conductive regions at an edge part of the package substrate. The stress release portion has different widths on both sides of the electrode separator interposed therebetween.
