Abstract: A method for forming a drying film of an organic electroluminescent device includes the steps of: providing a desiccant, and depositing the desiccant to form the drying film. The drying film is formed on a lid of the organic electroluminescent device or over a substrate thereof. Furthermore, an organic electroluminescent device is also disclosed. The organic electroluminescent device includes a substrate, a first electrode, an organic functional layer, a second electrode, a lid or passivation film, and a drying film. The substrate and the lid or passivation layer form an airtight space, in which the first electrode, organic functional layer and second electrode are located. In such cases, the drying film is formed with a deposition method.
