Abstract
A semiconductor light-emitting device includes a light-emitting member that includes a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, and a light-emitting layer between the first semiconductor layer and the second semiconductor layer, a first metal layer electrically connected to the first semiconductor layer, and a second metal layer electrically connected to the second semiconductor layer. The light-emitting member has a first surface including a front surface of the first semiconductor layer, a second surface including a front surface of the second semiconductor layer, a side surface including an outer periphery of the first semiconductor layer, and a recess extending inwardly of the second surface to an interior portion of the first semiconductor layer to expose an inner surface on a side of the recess facing the side surface.
