  • Touch panel and method for manufacturing the same
    Patent number: 9872400
    Abstract: The present disclosure provides a touch panel, including a substrate, at least one sensing electrode layer, a wire layer, a first light-shielding layer and a second light-shielding layer. The substrate has a visible region and a non-visible region. The wire layer corresponds to the non-visible region, wherein the wire layer includes signal lines and at least one gap therebetween, the signal lines electrically connect the sensing electrode layer. The first light-shielding layer is disposed within the non-visible region and between the substrate and the wire layer, wherein the first light-shielding layer includes at least one recess and a position of the recess corresponds to a position of the gap. The second light-shielding layer corresponds to the recess, wherein an area covered by the second light-shielding layer is equal to or greater than an aperture of the recess. The present disclosure also provides a method for manufacturing a touch panel.
