Disclosed are a light emitting device. The light emitting device includes first and second light emitting cells on a conductive support member and having a hole. The first and second light emitting cells includes first and second semiconductor layers, and an active layer. First and second conducive layers are between the first light emitting cell and the conductive support member, and a third and fourth conductive layers are between the second light emitting cell and the conductive support member. First insulating layer is between the second and fourth conductive layers and the conductive support member. Second insulating layer is disposed in the hole. The second conductive layer is electrically connected to the first light emitting cells through the hole and the third conductive layer.
