摘要： A light-emitting device includes a substrate including a first electrode group and a second electrode group, a first light emitting unit, a second light emitting unit, and a side wall. The first light emitting unit is provided on the upper surface of the substrate and electrically connected to the first electrode group. The second light emitting unit is provided on the upper surface of the substrate and electrically connected to the second electrode group. The side wall surrounds the first light-emitting unit and the second light-emitting unit. The first light emitting unit and the second light emitting unit are arranged side by side such that a separation space between the first light emitting unit and the second light emitting unit is smaller than a space between the second light emitting unit and an outer peripheral surface of the side wall.
