1. A conductive film, comprising:
a substrate;
a first metal nanowire layer disposed on a first surface of the substrate, wherein the first metal nanowire layer has a first anisotropy value larger than or equal to 2.8 and smaller than or equal to 4.0; and
a second metal nanowire layer disposed on a second surface of the substrate, wherein the second surface faces away from the first surface, and the second metal nanowire layer is more isotropic than the first metal nanowire layer, wherein the second metal nanowire layer has a second anisotropy value smaller than 2.0.
