Abstract
A touch panel defines a touch area and a reduced border area surrounding the touch area. The touch panel includes a substrate, a first conductive layer on the substrate, an insulating layer on the substrate and covering the first conductive layer, and a second conductive layer on the insulating layer. The second conductive layer includes first electrodes and strings of second electrodes in the touch area, each string of second electrodes extending in a first direction. The first conductive layer is conductive but almost opaque. The first conductive layer includes a decorative portion in the border area and first bridge portions in the touch area. Each first bridge portion is electrically coupled between adjacent two first electrodes in a second direction that intersects with the first direction. The decorative portion is configured to release static electricity and shield the border area.
