Patent ID: 8884921

Claim:
A display device comprising: a first substrate including a first surface, on which a touch by an external object occurs, and a second surface opposite to the first surface; a plurality of driving signal lines positioned on the second surface of the first substrate, wherein the plurality of driving signal lines transmits a driving signal for displaying an image; a plurality of pixels including a plurality of switching elements connected to the plurality of driving signal lines; a sensing signal line positioned on one of the first surface and the second surface of the first substrate, wherein the sensing signal line transmits a sensing signal generated based on the touch by the external object; a touch sensor unit including a sensing capacitor defined by at least one driving signal line of the plurality of driving signal lines and the sensing signal line; an insulating layer positioned on the second surface of the first substrate, wherein the sensing signal line is positioned between the insulating layer and the second surface of the first substrate, and wherein the plurality of driving signal lines is positioned on the insulating layer.
