A light-emitting device comprises a carrier, an insulated transparent adhesive layer, and a multi-layer epitaxial light-emitting structure located on the upper side of the insulated transparent adhesive layer. The top surface of the carrier comprises a first contact pad and a second contact pad. The insulated transparent adhesive layer is located on the upper side of the carrier, the first contact pad, and the second contact pad. The multi-layer epitaxial light-emitting structure comprises an active layer, a transparent layer located on the multi-layer epitaxial light-emitting structure, a third contact pad, and a fourth contact pad located on the multi-layer epitaxial light-emitting structure. At least one of surfaces of the first contact pad and the third contact pad facing the insulated transparent adhesive layer has a first plurality of protrusions. The first plurality of protrusions pierces the insulated transparent adhesive layer to electrically connect the first contact pad to the third contact pad. At least one of surfaces of the second contact pad and the fourth contact pad facing the insulated transparent adhesive layer has a second plurality of protrusions. The second plurality of protrusions pierces the insulated transparent adhesive layer to electrically connect the second contact pad to the fourth contact pad. |
