Abstract
Provided are charge-transporting varnishes that can form satisfactory thin films and can provide organic EL elements that can exhibit excellent emission efficiency and luminance characteristics when used for EL elements that have a structure on a substrate. The charge-transporting varnishes comprise quinone diimine derivatives represented by general formula (1) that are oligoaniline derivatives or oxides thereof, electron-accepting dopant substances or hole-accepting dopant substances, and at least one kind of silane compound. [In the formula, R, Rand Reach independently represents a hydrogen atom, a halogen atom, a hydroxyl group, etc. A and B each independently represents a divalent group represented by general formula (2) or (3). (In the formulas, R-Reach independently represents a hydrogen atom, a halogen atom, a hydroxyl group, etc.) m and n are each independently integers of 1 or greater and satisfy m+n≦20.]
