Title: ORGANIC EL DISPLAY DEVICE
Abstract:
The present invention is provided with: a base substrate (10); an organic EL element (18) that is provided on the base substrate (10); and a sealing film (25a) that is provided to cover the organic EL element (18). The sealing film (25a) has: a plurality of barrier layers (19a, 21a, 23a), each of which is formed of an inorganic film; and buffer layers (20a, 22a), each of which is formed of an organic film, and is provided between a pair of adjacent barrier layers (19a, 21a, 23a) among the barrier layers (19a, 21a, 23a). At the periphery of the organic EL element (18), the buffer layers (20a, 22a) respectively have flat thin film sections (20t, 22t) that are thinner than the film sections on the organic EL element (18).
