摘要：
An excellent Ed device having low driving voltage, high luminous efficiency and long life can be obtained by using a charge-transporting thin film composed of a charge-transporting varnish which contains an arylsulfonic acid compound represented by the formula (1) or (2) below as an electron-acceptor material especially in an OLED device or a PLED device. (1) (2) [In the formulae, X represents O, S or NH; A represents a naphthalene ring or anthracene ring having a substituent other than X and
