Abstract:
1. A method for producing a transparent conductive film comprising a transparent plastic film substrate and a crystalline transparent conductive layer provided on at least one surface of the transparent plastic film substrate, comprising: first depositing a first indium-based complex oxide having a first tetravalent metal element oxide in which a first content of the first tetravalent metal element oxide is 3 to 35% by weight on the transparent plastic film substrate by sputtering, wherein the deposited layer formed in the first depositing step has a first thickness of 9 to 34 nm, second depositing an indium oxide or a second indium-based complex oxide having a second tetravalent metal element oxide in which a second content of the second tetravalent metal element oxide is more than 0% by weight and not more than 6% by weight and lower than the first content by sputtering to form an amorphous transparent layer, wherein the deposited layer formed in the second depositing step has a second thickness of 1 to 17 nm, wherein each of the first and the second contents of the tetravalent metal element oxide content is expressed by the formula: {the amount of the tetravalent metal element oxide/(the amount of the tetravalent metal element oxide+the amount of indium oxide)}×100(%), crystallizing the amorphous transparent layer by heating to form the crystalline transparent conductive layer, wherein the heating is performed for less than 60 minutes.
