Abstract:
A substrate with a transparent conductive film, comprising:a transparent substrate, and a transparent conductive film formed on a surface of said transparent substrate; and a hole transport layer laminated on a surface of said transparent conductive film, wherein said transparent conductive film has a work function of 4.9 to 5.5 eV, a surface roughness of 1 to 10 nm, and a specific resistance of 1.6Ã—10âˆ’4 &OHgr;Â·cm or less, wherein said transparent conductive film is formed on the surface of said transparent substrate by an ion plating method by using indium tin oxide which is a mixture of tin oxide and indium oxide as a material to be vaporized, wherein said indium tin oxide has a tin oxide content of 4 to 6 wt %, and wherein an energy barrier between said transparent conductive film and said hole transport layer is equal to or smaller than 0.7 eV.
