Abstract: A light emitting device includes a resin package having a recess defined by a recess bottom surface and a recess lateral surface. The resin package includes a first lead including a first lead lower surface, a first lead upper surface, and an end portion. The light emitting element is mounted on the first lead upper surface opposite to the first lead lower surface. The light reflecting member is disposed on the recess bottom surface between the recess lateral surface and the light emitting element in a lateral direction. The end portion is provided between the first lead lower surface and the light reflecting member in the lateral direction. The end portion has a cross-sectional area viewed in the lateral direction which is smaller than a cross-sectional area of the first lead between the first lead lower surface and the first lead upper surface viewed in the lateral direction.

Abstract: A light emitting device includes a base structure, a wall, a light emitting element, a protection element, and a light reflective portion. The wall includes an inner peripheral surface defining an opening. The opening has a substantially polygonal shape in a planar view of the light emitting device. The light reflective portion has a maximum length which is longest in the light reflective portion. The maximum length is defined at a maximum-length position closest to the first corner among a plurality of positions defined in the light reflective portion. The light reflective portion has a minimum length which is shortest in the light reflective portion. The minimum length is defined at a minimum-length position arranged apart from the maximum-length position. The light reflective portion includes an inclined surface extending from the maximum-length position to the minimum-length position.
