Abstract
A touch panel has a substrate on which a first conductive layer, an insulating layer, a second conductive layer and a protective layer are formed in order. The second conductive layer and the first conductive layer form a touch-sensing area. The protective layer and the substrate have the same refractive index; and the first conductive layer, the insulating layer and the second conductive layer have the same refractive index so that the whole layered structure substantially has a symmetrical distribution of refractive indices, and leading to having optical characteristics of high transmittance and low reflectance.
