Claim:
1. A touch panel, which comprises: a substrate transparent to visible light; a first conductive micropattern including a plurality of first traces, the first traces defining a layout of a plurality of first cells in or on the substrate, the first cells being arranged in a two-dimensional array; and a second conductive micropattern including a plurality of second traces, the second traces defining a plurality of second cells electrically isolated with the first conductive micropattern and arranged in a two-dimensional array; the first conductive micropattern covering the second conductive micropattern; areas of the substrate respectively corresponding to the first cells as well as the second cells having different transmittances; the area of the substrate corresponding to the overlapped first and second cells cooperatively form a combination cell including one pair of first and second cells coincided with each other in an overlapping direction of the pair of first and second cells and thereby a plurality of the combination cells are defined, each of the combination cells has a corresponding integral transmittance and the integral transmittances of at least part of the combination cells are inconsistent due to the inconsistent alignment of crystalline grain in different locations of the substrate corresponding to the combination cell; wherein widths of the first traces and of the second traces each are 0.5˜10 μm, and an average transmittance of the substrate is at least 60%.
