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.
