Method for manufacturing organic light emitting device and solution for organic light emitting device

摘要

According to one embodiment, a method is disclosed for manufacturing an organic light emitting device (10). The organic light emitting device (10) includes an anode layer (110), a cathode layer (120), an emission layer (130) provided between the anode layer (110) and the cathode layer (120), and an intermediate layer (140) provided between the emission layer (130) and the cathode layer (120). The method can include applying a first solution containing a first organic material and a first solvent on the anode layer (110) to form the emission layer (130). The method can include applying a second solution on the emission layer (130) to form the intermediate layer (140), the second solution containing a second organic material with low molecular weight and a second solvent. The second solvent contains an acetylene alcohol-based surfactant (143) and has a solubility parameter smaller than a solubility parameter of the first solvent.
