It is an object of the present invention to provide a display device that has a structure of an electrode where a residue of a transparent conductive film is not generated when a weak acid solution is used in etching, which is particularly appropriate for an electrode of a light-emitting element. The illustrated spouted container broadly includes a storage container, a self-venting spout removably coupled to the container, a collar for removably coupling the spout to the container, and a cap for closing the spout andor the container. A temperature of from 102 to <120 C.
