ABSTRACT:
A charge-transporting varnish is disclosed which comprises a charge-transporting material composed of an oligoaniline compound represented by the formula (1) below and at least one kind of solvent. In this charge-transporting varnish, the charge-transporting material is dissolved or homogeneously dispersed in the solvent. By using this varnish, a charge-transporting thin film having excellent conductive characteristics can be formed through a short-time firing. In particular, when the varnish is applied to an OLED element or a PLED element, the resulting element can achieve excellent element characteristics such as low driving voltage, high luminous efficiency and long life
