1. A transparent conductive film comprising:
a substrate;
a metal nanowire layer disposed on the substrate; and
a water blocking protective layer, which has water absorbing particles and is disposed on the metal nanowire layer;
wherein the transparent conductive film has a first absorption peak in a 2750 cm−1 to 3000 cm−1 wavenumber region and a second absorption peak in a 3000 cm−1 to 3750 cm−1 wavenumber region using Fourier-transform infrared spectroscopy (FTIR) detection, a ratio of a maximum peak intensity of the second absorption peak to a maximum peak intensity of the first absorption peak ranges from 0.18 to 0.50, and a haze value of the transparent conductive film is 1.7% or less, and a volume percentage of the water absorbing particles in the water blocking protective layer ranges from 1% to 5%.
