A ZnO-based transparent conductive film has practicable moisture resistance, desired characteristics of a transparent conductive film, and excellent economy. The transparent conductive film is produced by growing ZnO doped with a group III element oxide on a substrate and has a region with a crystal structure in which a c-axis grows along a plurality of different directions. The transparent conductive film produced by growing ZnO doped with a group III element oxide on a substrate has a ZnO (002) rocking curve full width at half maximum of about 13.5° or more.
ZnO is doped with a group III element oxide so that the ratio of the group III element oxide in the transparent conductive film is about 7% to about 40% by weight.
The transparent conductive film is formed on the substrate with a SiNx thin film provided therebetween.
The transparent conductive film is formed on the substrate by a thin film formation method with a bias voltage applied to the substrate.
