TRANSPARENT SUBSTRATE WITH CONDUCTIVE MULTILAYER ANTI REFLECTION FILM, TRANSPARENT TOUCH PANEL USING THE TRANSPARENT SUBSTRATE WITH MULTILAYER ANTI REFLECTION FILM AND ELECTRONIC APPARATUS USING THE TOUCH PANEL

摘要

With objectives of providing with a transparent board with conductive multi-layer antireflection thin films, under condition of high transmissivity not only on a glass substrate but also on a non-glass transparent substrate with property of demanded electrical resistance at the most exterior surface, this invention laminates at least three layers of thin films on a transparent substrate, in which the transparent dielectric 1^st-layer thin film on the substrate that has a higher refractive index than the substrate has, the transparent dielectric 2^nd-layer thin film next to the 1st layer that has a lower refractive index than the substrate has, and the most exterior transparent conductive transparent thin film that includes weight percentage no less than 20% of SnO₂.
