In sum, the contact panel that the utility model embodiment provides and its manufacture method, this contact panel and its manufacture method can see through the conductor length that increases one end, the contiguous viewing area of the substrate upper periphery of tool touch-control array in contact panel lead-in wire, the spacing going between between one end, contiguous viewing area to shorten those peripheries.Accordingly, to prop up equably substrate, the surface of substrate can, because of connecting lead wire region and the different generation distortion of contraction in non-lead region, effectively not avoided in edge, visible area generation water ripple phenomenon in pressing process, improved display quality.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
