An optically consistent transparent conductive film and a preparation method thereof solve the problems of obvious etching marks, poor optical stability, easy corrosion of nanomaterials, and migration of metal ions of the metal nanowire transparent conductive film. The addition of nanoparticles with a matchable refractive index and a high corrosion resistance, the addition of an optical compensation layer, the use of a substrate with an anti-glare layer and other such means can solve the problem of obvious post-treatment etching marks of metal nanowire conductive films. A dense full-plate conductive transparent conductive film with improved corrosion resistance can be achieved by using an electric compensation layer. An ultraviolet stabilizer is added into a protective solution to improve the optical stability of the conductive film. An antioxidant, a dendrimer, and a complexing agent in the protective solution solve the problem of easy corrosion of nanomaterials and migration of metal ions.
