Abstract:
A light-emitting device includes a substrate including a mirror surface region on its upper surface, a semiconductor light-emitting element disposed in the mirror surface region, and an encapsulating layer joined onto the upper surface of the substrate. The encapsulating layer includes a lower layer that is in contact with the upper surface of the substrate, covers the surrounding of the semiconductor light-emitting element, and contains phosphor; and an upper layer that is positioned on the lower layer, and has a larger phosphor content per unit area than that of the lower layer.
