Abstract:
A light-emitting device includes a light-emitting element, a light-transmissive member, and a first light adjustment member. The light-transmissive member has a first upper surface, a second upper surface, a lower surface facing a first surface of a support substrate of the light-emitting element, a first lateral surface contiguous with the first upper surface and the second upper surface, a second lateral surface contiguous with the second upper surface and the lower surface, and a third lateral surface contiguous with the first upper surface and the lower surface. The first light adjustment member exposes the first upper surface of the light-transmissive member and covers the second upper surface and the first lateral surface of the light-transmissive member. The light-transmissive member and the first light adjustment member collectively define a rectangular cross-sectional shape.
