PURPOSE: A transparent conductive membrane circuit composition and a method for forming a transparent conductive membrane circuit composition of a display device substrate by using the composition are provided, to enable a transparent conductive membrane circuit having high transparency, light permeability and adhesive strength to be prepared even at a low temperature. CONSTITUTION: The composition comprises an ITO precursor; and an organic polymer conductive polymer or an organic polymer dielectric polymer. Preferably the ITO precursor is prepared by dissolving an organometallic alkyl compound such as In(CH3)3, In(C2H5)3, Sn(CH3)4 and Sn(C2H5)4, an organometallic alkoxide compound such as In(OC2H5)3, In(C3H7)3, In(OC4H9)3, Sn(OC2H5)4, Sn(OC3H7)4, Sn(OC4H9)4, Sn(C5H7O2)2 and Sn(C5H9) and an organometallic acetyl acetone compound such as In(C5H7O2)2, In(C5H7O2)3, In((C5H7)2)3, In(C6H5)3, Sn(C5H7O2)2 and Sn(C5H9)4 in 1,2-dimethoxyethane or diglyme to adjust the ratio of Sn to In to be 100:2.5 to 100:10, thereby preparing a colorless and viscous liquid; and the organic polymer conductive polymer or the organic polymer dielectric polymer is at least one selected from the group consisting of polyethylene dioxythiophene, polystyrene sulfonate, polyalkyl fluorene, polyphenyl vinylene, polythiophene and polyvinyl carbazole. |
