Abstract
A manufacturing method for an EL device including a mother substrate and a layered body including a light emitting element, the method includes irradiating a laser beams to peel the mother substrate and the layered body from each other, wherein the mother substrate and the layered body contact with each other via a resin layer of the layered body, a protection material is formed on a face of the layered body, the face of the layered body not contacting with the mother substrate, the irradiating includes irradiating a first laser beam and a second laser beam after the first laser beam, and an absorption rate of the second laser beam irradiation by the resin layer is greater than an absorption rate of the second laser beam irradiation by the protection material.
