A method for manufacturing a transparent gas barrier film for an organic electroluminescence element having a substrate with a gas barrier layer thereon. The gas barrier layer is formed on the substrate by plasma CVD using an organic silicon compound as a raw material gas and an oxygen gas as a decomposition gas. Formation of the gas barrier layer is carried out so that a carbon content of the gas barrier layer in the thickness direction repeatedly changes more than two times from high value, via intermediate value, low value and intermediate value, to high value.

Method for manufacturing a transparent gas barrier film

Disclosed is a thin film forming apparatus which is a plasma discharge processing apparatus for performing a plasma discharge processing on the surface of a continuously transported base at or near atmospheric pressure, wherein a reverse flow of the processing gas is prevented and thus a thin film having good quality is formed by a uniform gas flow. The thin film forming apparatus is characterized by having an auxiliary gas discharge means for discharging an auxiliary gas for preventing a reverse flow of the processing gas. Also disclosed are a thin film forming method, and a thin film.
