Abstract:
1. A flexible organic electro-luminescence device comprising: a substrate of 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, having 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 both 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, wherein the reflective layer is removed in the region corresponding to the contact hole, wherein the organic film, the inorganic film, the adhesive film and the protective film are sequentially formed on a whole side of the cathode electrode such that the films are stacked above the cathode electrode one another, and wherein the adhesive film includes a moisture absorbent, wherein the planarization layer includes, an organic film, on the substrate, having a thickness of about 3 mm˜5 mm to compensate the harshness of the surface of the substrate; and an inorganic film, on the organic film, having a thickness of about 100 Å˜300 Å.
