Abstract
To provide a method for producing an organic electroluminescent device having luminescent characteristics of high efficiency and prolonged lifetime and in which the occurrence of defects is suppressed, the organic electroluminescent device, and an electronic apparatus. A method for producing an organic electroluminescent device including a first electrode, a second electrode, and a functional layer disposed between the first electrode and the second electrode, the functional layer including at least a luminescent layer, the method includes the steps of mixing a solvent and a functional material to produce a functional solution; and applying the functional solution to form the functional layer by a wet film formation process, wherein, before the functional solution is produced, the solvent is subjected to dehydration and deoxygenation in order to remove water and oxygen in the solvent.
