Claim Text:
1. A light emitting device comprising: a base structure including a first surface; a wall provided on the first surface of the base structure, the wall including an inner peripheral surface defining an opening, the opening having a substantially polygonal shape in a planar view of the light emitting device, the substantially polygonal shape including a first corner, a second corner, a third corner, and a fourth corner; a light emitting element provided in the opening in the planar view and provided on the first surface; a protection element provided in the opening in the planar view and provided on the first surface, the protection element being closer to the first corner than to each of the second corner, the third corner, and the fourth corner in the planar view; and a light reflective portion covering the protection element, the light reflective portion being provided on the first surface, the light reflective portion having a maximum length which is defined from the first surface in a first direction and which is longest in the light reflective portion, the first direction being substantially perpendicular to the first surface, the maximum length being 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 having a minimum length which is defined from the first surface in the first direction and which is shortest in the light reflective portion, the minimum length being defined at a minimum-length position arranged apart from the maximum-length position, the light reflective portion including an inclined surface extending from the maximum-length position to the minimum-length position.
