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.
