| 摘要 |
An electroluminescent device includes a heat-conductive substrate, a heat-conductive adhering layer, a heat-conductive insulating layer, a reflective layer, a light-emitting diode element, a first contacting electrode and a second contacting electrode. The heat-conductive adhering layer is formed on the heat-conductive substrate. The heat-conductive insulating layer is formed on the heat-conductive adhering layer. The reflective layer is formed on the heat-conductive insulating layer. The light-emitting diode element is formed on the reflective layer, and a part of the reflective layer is exposed from the light-emitting diode element. The first contacting electrode is disposed on the light-emitting diode element. The second contacting electrode is disposed on the exposed reflective layer. A manufacturing method of the electroluminescent device is also disclosed.
