ABSTRACT:
A transparent conductive thin film which can be produced easily by sputtering or the like with a sintered target, needs no post-treatment such as etching or grinding, is low in resistance and excellent in surface smoothness, and has a high transmittance in the low-wavelength region of visible rays; and transparent, electroconductive substrate for a display panel and an organic electroluminescence device excellent in light-emitting characteristics, both including the transparent conductive thin film. More particularly, a transparent conductive thin film comprising indium oxide as the major component and silicon as a dopant, having a substantially amorphous structure, wherein silicon is incorporated at 0.5 to 13% by atom on indium and silicon totaled; and a transparent conductive thin film comprising indium oxide as the major component and tungsten and germanium, wherein tungsten is incorporated at a W/In atomic ratio of 0.003 to 0.047 and germanium is incorporated at a Ge/In atomic ratio of 0.001 to 0.190.
