Abstract:
A barrier film configured to reduce degradation of an organic EL element includes a first inorganic film, a second inorganic film, and a third inorganic film which are provided in order from a base substrate, a first organic film between the first inorganic film and the second inorganic film, and a second organic film between the second inorganic film and the third inorganic film. The first organic film has a plurality of first through holes formed therein so that the first inorganic film is in contact with the second inorganic film through the first through holes. The second organic film has a plurality of second through holes formed therein so that the second inorganic film is in contact with the third inorganic film through the second through holes.
