Beschreibung
Zusammenfassung:	Disclosed is an ink composition for an organic EL thin film, that is, an ink composition for the formation of an organic EL thin film including an organic EL material, a liquid crystalline compound with a bandgap of 3.5 eV or more, and a solvent having an organic compound. Furthermore, the liquid crystalline compound preferably contains no functional group of -CN, -OH, or -F. Moreover, the liquid crystalline compound preferably has a molecular dipole moment of 4.0 debyes or less.
