Abstract
A functional layer forming composition is capable of obtaining a stable film forming property when a liquid phase process is used. A method produces a functional layer forming composition. A method produces an organic EL element. An organic EL device and an electronic apparatus are also described. A functional layer forming composition is used when at least one layer in a functional layer containing an organic material is formed by a liquid phase process, and is characterized in that the composition includes a solid component for forming a functional layer, a first aromatic solvent having an electron withdrawing group, and a second aromatic solvent having an electron donating group, and the boiling point of the second aromatic solvent is higher than the boiling point of the first aromatic solvent.
