Light emitting device and manufacturing method thereof

The invention discloses a light-emitting device and a manufacturing method thereof. The light-emitting device comprises a substrate, a conductive circuit layer, a plurality of conductive connecting parts and a plurality of semiconductor light-emitting sources, the conductive circuit layer is located on the substrate. The conductive circuit layer comprises a plurality of conductive structures, each conductive structure is provided with at least one welding pad, and a gap is arranged between two adjacent conductive structures. Each conductive connecting part is arranged on each corresponding welding pad. Each semiconductor light-emitting source corresponds to each interval so as to be arranged on the two adjacent conductive connecting parts in a crossing mode, and then the semiconductor light-emitting sources are electrically connected to the welding pads of the two adjacent conductive structures. Therefore, the conductive connecting part can enable the connection between the semiconductor light-emitting source
