ORGANIC LIGHT EMITTING DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A method for manufacturing an organic light emitting device according to the present invention includes the steps of: forming a plurality of spacers and an organic light emitting layer on a substrate, such that the spacers are spaced apart from each other; introducing the substrate with the spacers and the organic light emitting layer into a vacuum-state chamber; filling a filler to coat the organic light emitting layer and hardening the resultant structure; applying a sealant to the space where the filler is not applied, from among the spaces formed between the spacers by the spacing of the spacers; disposing encapsulating portions onto the spacers, the sealant and the filler; encapsulating the chamber by hardening the sealant; and slowly venting the encapsulated vacuum-state chamber to remove air gaps formed between upper surfaces of the spacers, the sealant and the filler and the encapsulating portions. As described above, the present invention performs a first encapsulation by using the filler which is filled to coat the organic light emitting layer containing a protective layer, and performs a second encapsulation on the region of the substrate with no organic light emitting layer by using the sealant, thereby suppressing moisture and oxygen from entering the organic light emitting layer and thus improving the lifespan of the device.
