Abstract:
1. A light-emitting device comprises: a carrier, comprising a first contact pad and a second contact pad formed on a top surface; an insulated transparent adhesive layer, located on the carrier, the first contact pad, and the second contact pad; a multi-layer epitaxial light-emitting structure, located on the insulated transparent adhesive layer, and comprising a third contact pad and a fourth contact pad on a bottom surface of the multi-layer epitaxial light-emitting structure, wherein at least one of surfaces of the first contact pad and the third contact pad facing the insulated transparent adhesive layer having a first plurality of protrusions, which pierces the insulated transparent adhesive layer to electrically connect the first contact pad to the third contact pad, and at least one of surfaces of the second contact pad and the fourth contact pad facing the insulated transparent adhesive layer having a second plurality of protrusions, which pierces the insulated transparent adhesive layer to electrically connect the second contact pad to the fourth contact pad; and a light-pervious layer, located on the multi-layer epitaxial light-emitting structure.
