Abstract: A light-emitting device includes a package and at least one light-emitting element. The package includes a concave portion which has a bottom surface. The bottom surface includes sides, package distances between opposite sides among the sides, a longest package distance among the package distances, a lower side among the sides, and an upper side among the sides opposite to the lower side. The at least one light-emitting element is arranged on the bottom surface of the concave portion and has a polygonal shape viewed along a front direction. The polygonal shape has light-emitting element distances between vertexes of the polygonal shape and has a longest light-emitting element distance among the light-emitting element distances. The at least one light-emitting element is arranged such that a light-emitting element lateral line along the longest light-emitting element distance is substantially parallel to a package lateral line along the longest package distance.
