Abstract:
A thin film electronic device comprising:a carrier substrate; a laminate provided on the carrier substrate, and comprising a laminate structure having an insulating layer and a plurality of electrode layers, and wherein the insulating layer defines two or more gaps; a thin film element formed in the laminate with the insulating layer held between the electrode layers; and a plurality of terminal electrodes electrically connected to the corresponding electrode layers and respectively provided in the gaps for receiving electrical signals of different potentials applied thereto wherein the laminate is covered with a protective layer, wherein the protective layer has through-holes formed therein in the gaps, and the terminal electrodes are exposed in the through-holes, wherein the through-holes each have a diameter which gradually increases toward a surface of the protective layer apart from the electrode layers, wherein the through-holes each have an interior surface which is linearly inclined at an angle of 15 to 60 degrees with respect to the electrode layers located below the protective layer.
