Abstract
A substrate with a transparent condcutive film is provided, which has a high work function and an excellent surface smoothness as well as a reduced specific resistance to thereby ensure a reduced power consumption and enhanced display quality. An ITO film is formed on a glass substrate by an ion plating method by using an ITO sintered compact with an SnO content of 4 to 6 wt %. The ITO film obtained as above has a surface having a work function of 4.9 to 5.5 eV, a surface roughness of 1 to 10 nm, and a specific resistance of 1.6×10 &OHgr;·cm or less. An organic EL device using the substrate is provided, in which an organic multilayer film (hole transport layer , light-emitting layer , and electron transport layer ) is laminated on the surface of the ITO film , and further a metal thin film layer is laminated on the surface of the organic multilayer film.
