    Abstract: PURPOSE: An organic electroluminescence device with an encapsulation film formed by a wet process and a manufacturing method thereof are provided to lengthen the life span of a device by isolating moisture and oxygen when the organic electroluminescence device is running. CONSTITUTION: A transparent electrode(12) is formed on a substrate(10) made of a transparent glass or plastic material. The transparent electrode(12) is made of a first ITO(Indium-Tin-Oxide) electrode and a second ITO electrode, which are formed on an edge of the substrate(10). A hole injection layer(22) and a hole transportation layer(24) are sequentially deposited on the first ITO electrode of the transparent electrode(12). A tris-(8-hyfrooxyquinoline)aluminum is coated on the hole transportation layer(24) by vacuum depositing, to thereby form a luminous layer(26) and an electron transportation layer(28). An alloy is deposited on upper surfaces of the luminous layer(26) and the electron transportation layer(28), and a portion of upper surface of the second ITO electrode, to thereby form a metal electrode(30) for an anode.
