Abstract A transparent thin film desiccant capable of improving the storage reliability of OLED was developed, which was named OleDry. OleDry is an excellent desiccant mainly composed of aluminum complex, which well dissolves in hydrocarbon solvent. Taking advantage of the dissolubility of aluminum complex, transparent thin film can be formed by coating OleDry on the inner surface of the cover glass and drying it. Not only to the standard OLEDs, a thin transparent OLED, a top‐emission OLED and even a flexible OLED using resin substrate are viable with high storage reliability by the use of OleDry.
