Patent ID: 8647899

Claim:
A method for manufacturing an organic light emitting device, the method comprising: forming a thin film structure comprising an organic light emission layer on a first substrate; forming a passivation layer covering the thin film structure; forming a dehumidification buffer layer on a second substrate; forming an adhesive; combining the first substrate and the second substrate using the adhesive; and heat treating, after combining the first substrate and the second substrate, the dehumidification buffer layer to soften the dehumidification buffer layer such that the dehumidification buffer layer is in a flowing state, wherein the passivation layer is disposed between the thin film structure and the dehumidification buffer layer, and the dehumidification buffer layer completely covers an upper surface of the thin film structure, and wherein, after the combining of the first substrate and the second substrate but before the heat treating, the dehumidification buffer layer is spaced apart from the passivation layer.
