  • Publication number: 20110268870
    Abstract: In an apparatus for film formation, constituted so that an organic EL molecular gas is ejected into an ejection vessel, a plurality of organic EL material vessels are provided together with a piping system for connecting the plurality of organic EL material vessels to the ejection vessel. The plurality of organic EL material vessels are selectively put into a supply state of organic EL molecules. The piping system is constructed so that the carrier gas is fed into each organic EL material vessel in such a manner that the pressure during film formation and the pressure during non-film formation are equal to each other. During non-film formation, the carrier gas is allowed to flow from one of the organic EL material vessels to other material vessel.
