Abstract
A light-emitting device includes a package having a recessed portion defined by a bottom surface and lateral walls surrounding the bottom surface, first and second light-emitting elements aligned in the longitudinal direction on the bottom surface, and a wavelength conversion member in the recessed portion, the wavelength conversion member converting light from the first light-emitting element. The first and second light-emitting elements each have a polygonal shape other than a rectangular shape in a front view. The first and second light-emitting elements are disposed away from each other so that a longest side of each light-emitting element will be substantially parallel to the longitudinal direction of the bottom surface and so that sides facing each other will be substantially parallel to each other. The wavelength conversion member is disposed at least in a region on the bottom surface between the first and second light-emitting elements.
