It is provided a contacting method when a plurality of films to be peeled are laminating. Reduction of total layout area, miniaturization of a module, weight reduction, thinning, narrowing a frame of a display device, or the like can be realized by sequentially laminating a plurality of films to be peeled which are once separately formed over a plastic film or the like. Moreover, reliable contact having high degree of freedom is realized by forming each layer having a connection face of a conductive material and by patterning with the use of a photomask having the same pattern.
