Abstract:
A solution contains a functional material for constituting a function layer, and a solvent. The solvent contains a high-boiling-point solvent composed of one or more solvent components having a boiling point of not less than 200° C. The high-boiling-point solvent has a viscosity of from 13 mPa·s to 25 mPa·s, inclusive, and a surface tension of from 33 mN/m to 37 mN/m, inclusive.
