A method of hiding transparent electrodes on a transparent substrate coats a solution of non-conductive nanoparticles onto the transparent substrate and the transparent electrodes after forming a plurality of transparent electrodes on the transparent substrate, and both non-conductive nanoparticles and transparent electrodes have the same reflective index of light. After a high-temperature thermal processing is performed to the transparent substrate, an even mask is formed on the transparent substrate and the transparent electrodes, such that the non-conductive nanoparticles in the mask provide the same reflective index of light for the positions of the transparent substrate with and without the transparent electrodes, so as to effectively prevent a different reflective index of light at any position of the transparent substrate that will cause a poor image quality of the screen.
