1. A touch panel comprising:
a cover substrate including an active area and an inactive area;
sensing electrodes including first sensing electrodes and second sensing electrodes on the active area, the first sensing electrodes being insulated from the second sensing electrodes;
a bridge electrode connecting with the first or the second sensing electrodes on the active area;
a first printing layer on the inactive area;
a second printing layer on the first printing layer;
a wire electrode on the second printing layer;
a conductive layer connecting the sensing electrodes with the wire electrode, the conductive layer being on the first printing layer;
the conductive layer including a first conductive layer and a second conductive layer; and
an insulating layer interposed between the first and second conductive layers on the inactive area;
wherein the second printing layer has a width smaller than a width of the first printing layer,
wherein the first and second conductive layers extend along a side surface of the first printing layer to a top surface of the first printing layer,
wherein the second conductive layer extends to a side surface of the second printing layer,
wherein the first conductive layer is in direct physical contact with the side surface of the first printing layer and the side surface of the second printing layer, and extends continuously from the side surface of the first printing layer to the side surface of the second printing layer;
wherein the wire electrode makes contact with the second conductive layer,
wherein the second conductive layer is electrically connected to the bridge electrode, the first sensing electrode, or the second sensing electrode,
wherein the insulating layer includes an open area through which the first conductive layer is electrically connected to the second conductive layer, and
wherein the first conductive layer makes contact with the second conductive layer through the open area.
