    Abstract: A light-emitting device includes a light-emitting element, a light-transmissive member, and a light adjustment member. The light adjustment member exposes a first upper surface and covers a second upper surface and a first lateral surface of the light-transmissive member. The light-transmissive member has a thickness from a lower surface to the first upper surface larger than a thickness from the lower surface to the second upper surface. In a plan view, first and second light-emitting regions have the first and second upper surfaces of the light-transmissive member, respectively, and an area of the second light-emitting region is in a range from 35% to 95% of an area of a light-emitting region. A boundary between the first and second light-emitting regions includes first and second points on a perimeter of a light-emitting region, and a straight line connecting the first and second points extends across the light-emitting region.

    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.

    Abstract: A light emitting element includes a semiconductor layered body, an insulating film, first and second electrodes, and first and second external connection parts. The first semiconductor layer is exposed from the light emitting layer and the second semiconductor layer at exposed portions arranged in columns each extending in a first direction. The insulating film defines openings respectively located above the exposed portions. The first electrode is connected to the first semiconductor layer through the openings and covers a part of the second semiconductor layer via the insulating film. The first external connection part is connected to the first electrode and spaced apart from the exposed portions in the plan view. The first external connection part has a shape elongated in the first direction between adjacent ones of the columns of the exposed portions. The second external connection part is connected to the second semiconductor layer via the second electrode.

    Abstract: A light-emitting device includes a light-emitting element configured to emit a first light, a wavelength conversion member disposed on an upper surface of the light-emitting element and configured to emit, by excitation by the first light, a second light having a peak wavelength longer than a peak wavelength of the first light, and a covering member disposed around the light-emitting element and the wavelength conversion member and containing a light-reflective material and a phosphor. The phosphor is configured to emit, by excitation by the first light, a third light having a peak wavelength longer than the peak wavelength of the second light. The content of the phosphor above the upper surface of the light-emitting element is less than the content of the phosphor below the upper surface of the light-emitting element.
