Abstract:
By using a charge-transporting thin film which is made of charge-transporting varnish containing, as an electron-acceptor material, a 1,4-benzodioxane sulfonic acid compound represented by the formula (1) below especially in an OLED device or a PLED device, there can be realized excellent EL device characteristics such as low driving voltage, high luminous efficiency and long life.
