Abstract
A flexible organic electro-luminescence device is adapted to improve its flexibility and to completely and substantially exclude the intrusion of external moisture and/or oxygen. The flexible organic electro-luminescence device includes: a substrate of a thickness of about 0.05 mm˜0.2 mm; a planarization layer on the substrate; a thin film transistor on the planarization layer; a passivation layer on the planarization layer and the thin film transistor, with a contact hole exposing a drain electrode of the thin film transistor; a reflective layer on the passivation layer; an anode electrode on the reflective layer, electrically connected to the drain electrode of the thin film transistor; a bank layer on the edge region of the anode electrode and the passivation layer, including an organic material; an organic light emitting layer on the anode electrode; a cathode electrode on the bank layer and the organic light emitting layer; and a seal layer on the cathode electrode, including an organic film, an inorganic film, an adhesive film and a protective film.
