Abstract
An organic light-emitting device capable of reducing ambient-light-reflection from a cathode includes a light-transmissive substrate, a light-transmissive anode, an organic light-emitting structure, a semi-transparent cathode having a work function below 4.0 eV and a refractive index greater than 1, and a multilayer structure, which is combined with the cathode to reduce reflection of ambient-light entering the device.
