    Abstract: A light-emitting device having light-emitting elements with high operation stability and light extraction efficiency is provided. The light-emitting device includes: a substrate; light-emitting elements aligned and arranged on the substrate in an arrangement direction; wavelength conversion layers each disposed on each of the light-emitting elements with a light-transmitting adhesive interposed therebetween, each of the wavelength conversion layers having an upper surface smaller than a bottom surface, and a side surface shape in which a length in a lateral direction parallel to the bottom surface and perpendicular to the arrangement direction decreases from the bottom surface toward the upper surface; a light-transmitting plate disposed over the wavelength conversion layers; and a reflective resin covering side surfaces of the light-emitting elements, the wavelength conversion layers, and the light-transmitting plate. A side surface of the wavelength conversion layer facing to another adjacent wavelength conversion layer extends in a direction perpendicular to the substrate.

    Abstract: A light-emitting device according to the present invention comprises: a mounting board; a plurality of light-emitting elements that each include a supporting substrate and a semiconductor structure layer, the supporting substrate being disposed on the mounting board, and the semiconductor structure layer being formed on the supporting substrate and including a light-emitting layer, a wavelength conversion member that covers the plurality of light-emitting elements above the light-emitting elements and converts a wavelength of a light emitted from the light-emitting layer; a translucent member that covers a lower surface of the wavelength conversion member and covers the semiconductor structure layer on the supporting substrate; and a resin member filled between the plurality of light-emitting elements, the resin member being formed of a resin material containing particles having a light reflectivity. The translucent member includes a thin film portion having a constant film thickness between the wavelength conversion member and the resin member in a region between the plurality of light-emitting elements, and the constant film thickness is smaller than a distance between a top surface of the supporting substrate and a lower surface of the wavelength conversion member.

    Abstract: A light-emitting device includes a substrate, a frame body, a light-emitting element, a wavelength converter, and a light reflecting portion. The light-emitting element includes a semiconductor light-emitting layer on a support substrate. The wavelength converter is disposed on an upper surface of the light-emitting element. The light reflecting portion covers side surfaces of the light-emitting element and the wavelength converter and is formed of a translucent resin containing light reflective particulate fillers. The light reflecting portion includes a first region extending along an upper surface of the light reflecting portion, a second region that is disposed under the first region and has a content rate of the particulate fillers lower than a content rate of the first region, and a third region that is disposed under the second region and has a content rate of the particulate fillers lower than the content rate of the second region.
