Abstract:
1. An organic EL device, comprising: a substrate; an anode arranged on the substrate; a hole injection layer of transition metal oxide arranged on the anode; an organic light emitting layer arranged on the hole injection layer; a cathode arranged on the organic light emitting layer; an inorganic film arranged on the substrate; and a bank comprising a fluorine-containing resin arranged on the inorganic film; wherein: the bank and the inorganic film define a region of the organic light emitting layer, and an edge of a top surface of the organic light emitting layer contacts a face of the bank; a distance between an end portion of a bottom face of the bank and an end portion of a top face of the inorganic film is not greater than 5 μm; and a bottom face of the inorganic film extends in a region defined by the bank and the inorganic film that is beyond the top face of the inorganic film, a wettability of a top face of the bank is lower than a wettability of a wall face of the bank; and a wettability of the wall face of the bank is lower than a wettability of the inorganic film.
