Title: ORGANIC EL ELEMENT AND METHOD FOR MANUFACTURING SUBSTRATE
Abstract:
A method for manufacturing a substrate 10 according to an embodiment is provided with: a resin film formation step in which a resin film containing a transparent resin material to become a transparent resin filler 16 is formed on the obverse surface 12a of a transparent resin film 12 on which metal wiring 14 of a predetermined pattern having a plurality of openings 18 is formed, the resin film being formed so as to embed the metal wiring 14; a photocuring step in which, after the resin film formation step, visible light is irradiated from the reverse surface 12b side of the transparent resin film 12 so as to photocure the resin film in the openings 18; a developing step in which, after the optical curing step, a the resin film is subjected to a development process to remove the resin film on the metal wiring 14; and a thermal curing step in which, after the resin film on the metal wiring 14 is removed, the resin film left on the transparent resin film 12 is subjected to a heat treatment so as to heat-cure the resin film, thereby forming the transparent resin filler 16. Each of the openings 18 is filled with the transparent resin filler 16. The transparent resin material is thermosettable and is photocured by visible light.
