Abstract:
An organic EL display device includes an organic EL element and a sealing film. The organic EL element is formed over a display region of a base substrate. The sealing film covers the organic EL element. The sealing film includes a first barrier layer, a buffer layer, and a second barrier layer. The first barrier layer includes a first inorganic film and is disposed on the surface of the organic EL element. The buffer layer includes an organic film and is disposed on the surface of the first barrier layer. The second barrier layer includes a second inorganic film and is disposed on the surface of the buffer layer. The first barrier layer includes micropores in the surface, the surface being in contact with the buffer layer.
