Abstract: A plurality of light-emitting devices (10) include a plurality of light-emitting devices (10a), a plurality of light-emitting devices (10b), and a plurality of light-emitting devices (10c). The plurality of light-emitting devices (10) are aligned on a reflecting member (20). Six light-emitting devices (10c) are aligned in a straight line along one direction. Four light-emitting devices (10b) are aligned surrounding a region facing one ends of the six light-emitting devices (10c). Each of four light-emitting devices (10a) are aligned with each of the four light-emitting devices (10b) outside the four light-emitting devices (10b).

Abstract: A light-emitting device (20) includes a first light-emitting member (10a) and a second light-emitting member (10b). Each of the first light-emitting member (10a) and the second light-emitting member (10b) includes a first surface (12) and a second surface (14), and light is emitted from the first surface (12). The first light-emitting member (10a) includes a first region (16a) and a second region (16b), the first region (16a) of the first light-emitting member (10a) being located on the second surface (14) side of the second light-emitting member (10b) and the second region (16b) of the first light-emitting member (10a) being located on the first surface (12) side of the second light-emitting member (10b).
