Claim:
1. A touch panel, comprising: a cover plate; a sensor electrode layer, disposed on the cover plate, wherein the sensor electrode layer comprises: a plurality of first axis electrodes, wherein each first axis electrode comprises a plurality of first electrode blocks arranged along a first direction, and the first electrode blocks are electrically connected to each other; a plurality of second axis electrodes, wherein each second axis electrode comprises a plurality of second electrode blocks arranged along a second direction, and the second electrode blocks are electrically isolated from each other; a plurality of bonding pads, disposed on the periphery region of the cover plate; and a plurality of first periphery traces, which are electrically connected to the bonding pads and the first axis electrodes or the second axis electrodes respectively; an insulating layer, disposed on the sensor electrode layer, wherein a plurality of first via holes and a plurality of second via holes are formed on the insulating layer, wherein each first via hole exposes the first axis electrodes or the second axis electrodes that are not electrically connected to the first periphery traces, and each second via hole exposes parts of the second electrode blocks of the second axis electrodes; and a jumper layer, disposed on the insulating layer, wherein the jumper layer comprises a plurality of jumper traces and a plurality of second periphery traces, wherein the second periphery traces are electrically connected to the first axis electrodes or the second axis electrodes through the first via holes, and the jumper traces are electrically connected the second electrode blocks of the second axis electrodes through the second via holes, wherein the first axis electrodes or the second axis electrodes are not electrically connected to the first periphery traces; and the touch panel further comprising a top insulating layer disposed on the jumper layer and a plurality of third via holes disposed on the top insulating layer, exposing the jumper layer; wherein the jumper layer is electrically connected to external traces through the third via holes.
