Abstract

A light-emitting device includes a plurality of light-emitting elements, a plurality of light-transmissive members, and a covering member. The light-emitting elements each has a light-extracting surface. The light-emitting elements each includes a layered structure including a semiconductor layer, and a plurality of electrodes connected to the layered structure. The light-transmissive members each has a lower surface facing the light-extracting surface of at least one of the light-emitting elements, and an upper surface opposite to the lower surface and having an area smaller than an area of the lower surface. The upper surface of each of the light transmissive members collectively constitutes a light-emitting part having an outermost periphery with a square shape or a circular shape. The covering member integrally covers lateral surfaces of the light-emitting elements and lateral surfaces of the light-transmissive members.
