Abstract: A light emitting device includes a package having a recess which includes a bottom surface. A first bottom surface of a first light emitting element is put on a first part of the bottom surface. A second bottom surface of a second light emitting element is put on the first part of the bottom surface. A first side surface of the first light emitting element is opposite to a second side surface of the second light emitting element with a gap. At least a part of the first side surface does not overlap with the second side surface viewed in a direction perpendicular to the first side surface. A protection element is provided at a second part of the bottom surface. A light reflective material covers the protection element.

Abstract: A light emitting device includes a package having a recess which includes a bottom surface having corners. The package includes a first electrode, a second electrode, and a resin portion. The first electrode is provided at a first part of the bottom surface. The second electrode is provided at a second part of the bottom surface. The resin portion is provided between the first electrode and the second electrode at a third part of the bottom surface. A protection element is provided on the bottom surface. A light reflective material covers the bottom surface except for an uncovered region to cover the protection element and the corners of the bottom surface and uncovers an uncovering region of the bottom surface. The uncovered region is defined by linear lines and curved lines connecting the linear lines. A light emitting element is provided in the uncovered region on the bottom surface.
