The touch panel 2 includes a substrate 21, a conductive layer 22, an insulating layer 23, and an optical paint layer 24. Like the material f of the insulating layer 13 described above, the optical coating layer 24 can also be formed to have a refractive index close to that of the conductive layer 22, ranging from plus or minus 0.05 β of the conductive layer 22. The first embodiment and the second embodiment are combined, and the difference is that the difference in the optical coating layer 24 formed on the insulating layer 23 is obtained, but there is no difference in efficacy. Therefore, the technical feature to be emphasized is that the shielding optical interference fringes are not limited to the position of the film layer (optical coating layer 24) whose refractive index needs to be controlled, as long as the same purpose can be achieved. Through the technical content disclosed above, a capacitive touch panel that meets market demands can be fabricated after the circuit is disposed on the conductive layer without causing optical interference fringes and reducing material cost.
