Claim Text:
1. A method for manufacturing a transparent conductive film using a one-component type transparent conductive film coating solution including a polar solvent, a non-polar solvent, a conductive metal ink, and a volatile surfactant, the method comprising: a) forming a coating film by coating a one-component type transparent conductive film coating solution on a substrate, the one-component type transparent conductive film coating solution including all of the following: a non-polar solvent; a polar solvent non-miscible with the non-polar solvent; a conductive metal ink miscible with any one of the non-polar solvent and the polar solvent; and a volatile surfactant having a faster evaporation rate than the non-polar solvent and the polar solvent, and solubility with respect to the conductive metal ink, the polar solvent, and the non-polar solvent; and b) forming a conductive pattern having a hole type transmissive part and a pattern part formed of the conductive metal ink, on the substrate, by drying and burning the coating film, comprising: b1) evaporating the volatile surfactant first, thereby allowing phase separation into two non-miscible phases, the phase separation occurring into one solvent containing the conductive metal ink and the other solvent, depending on the miscibility with the conductive metal ink between the non-polar solvent and the polar solvent; and b2) allowing the non-polar solvent and the polar solvent to evaporate in a phase separation state, to thereby form the transmissive part which is formed in an empty space by evaporating a solvent of the polar solvent and the non-polar solvent having non-affinity with the conductive metal ink, and the pattern part in which the conductive metal ink having affinity with any one solvent of the polar solvent and the non-polar solvent is left, wherein water condensation does not occur while the polar and non-polar solvents evaporate.
