Abstract
An anode 2 is formed on an element substrate 1. By using a film-forming solution containing a stacking material that forms an organic layer 43, a film is formed on a donor substrate 10 to pattern a transfer layer 11, thereby fabricating a transfer substrate 12. The transfer substrate 12 and the element substrate 1 are placed so as to face each other with spacers 13 interposed therebetween, such that the surface of the transfer substrate 12, which has the transfer layer 11 formed thereon, faces the element substrate 1 having the anode 2 formed thereon. The transfer substrate 12 and the element substrate 1 facing each other are held under vacuum conditions. The transfer substrate 12 is heated by a heat source 15 under the vacuum conditions to transfer the transfer layer 11 to the element substrate 1.
