Abstract:
1. A method for producing an organic EL device, the method comprising the steps of: preparing an adhesive sheet on which a resin substrate is laminated; allowing the resin substrate to adhere onto a hard substrate with the adhesive sheet interposed therebetween; forming an organic EL element on the resin substrate, thereby producing an organic EL device including the resin substrate and the organic EL element; peeling the organic EL device from the hard substrate; wherein the adhesive sheet comprises a first adhesive layer for being bonded to the hard substrate; a second adhesive layer formed on the first adhesive layer and bonded to the resin substrate; a non-adhesive region is defined at an end portion of the resin substrate, the non-adhesive region not overlapping with the second adhesive layer but overlapping with the first adhesive layer when projected in the thickness direction; and the organic EL device is peeled from the non-adhesive region of the hard substrate.
