Abstract: The yield of a separation process is improved. The mass productivity of a display device which is formed through a separation process is improved. A layer is formed over a substrate with use of a material including a resin or a resin precursor. Next, a resin layer is formed by performing heat treatment on the layer. Next, a layer to be separated is formed over the resin layer. Then, the layer to be separated and the substrate are separated from each other. The heat treatment is performed in an atmosphere containing oxygen or while supplying a gas containing oxygen.
