A coating solution for the light extraction layer of an organic light emitting device and a method for manufacturing a light extraction substrate of an organic light emitting device by using it.

摘要

The coating solution for the light extraction layer of the organic light emitting device may contain light scattering particles containing metal oxides and a solvent. A method of manufacturing a light extraction substrate for an organic light emitting device is to use the coating solution to form a light extraction layer on the base substrate by inkjet coating or spray coating.
