Abstract
A main object of the present invention is to provide a method for manufacturing an EL element which can avoid a state which plural unnecessary layers are laminated on each pattern-formed light-emitting portion when the light-emitting portions are formed by photolithography and thus enables quick and easy peeling treatment in the peeling process of the unnecessary layers.
