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.

Abstract: A light-emitting device includes a plurality of light-emitting elements, a plurality of light-transmissive members, a covering member, and a plurality of pairs of electrodes. The light-emitting elements are arranged in a plurality of columns and a plurality of rows. The covering member integrally covers lateral surfaces of the light-emitting elements. The pairs of electrodes are arranged at a lower surface of the light-emitting device. The pairs of electrodes include first and second pairs of electrodes aligned along a column direction so that the electrodes of the same polarity among the first and second pairs of electrodes are aligned along the column direction, and a third pair of electrodes arranged adjacent to the first pair of electrodes in a row direction so that one of the third pair of electrodes and one of the first pair of electrodes facing each other in the row direction have the same polarity.

Abstract: A method of manufacturing a light emitting device includes: placing a light-emitting element above a light-transmitting portion of a first resin layer; placing a protective element above the first resin layer or a first surface of the light-emitting element; forming a second resin layer on the first resin layer so as to cover an entirety of the light-emitting element and an entirety of the protective element; removing a portion of the second resin layer such that an anode and a cathode of the light-emitting element and a first electrically-conductive structure and a second electrically-conductive structure of the protective element are exposed from the second resin layer; and forming a first electrode, which is electrically connected to the anode and the first electrically-conductive structure, and a second electrode, which is electrically connected to the cathode and the second electrically-conductive structure.
