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.
