Abstract:
1. A touch panel comprising: a substrate having a first refractive index; a first conductive layer having a second refractive index and being patterned and formed on the substrate; an insulating layer having a third refractive index and covering the first conductive layer; a shading layer being formed on the substrate and the insulating layer, surrounding the touch-sensing area and covering a periphery of the insulating layer; and a protective layer having a fifth refractive index and covering the second conductive layer, wherein the first refractive index and the fifth refractive index fall between 1.5 and 1.6, the second refractive index, the third refractive index and the fourth refractive index fall between 1.7 and 2.2, so that a multi-layer structure constituted by at least the substrate, the first conductive layer, the insulating layer, the second conductive layer and the protective layer has a symmetrical distribution of refractive index, and wherein the second conductive layer covers a periphery of the shading layer so that a portion of the shading layer is disposed between the insulating layer and the second conductive layer.
