Claim Text:
1. A display device, comprising: a substrate having a first surface and a second surface; a sensing capacitor having a first sensing electrode and a second sensing electrode as two terminals of the sensing capacitor, wherein the first sensing electrode and the second sensing electrode are disposed on the second surface; a first sensing signal line electrically connected with the first sensing electrode; a second sensing signal line electrically connected with the second sensing electrode; an insulating layer positioned on the first sensing electrode and the second sensing electrode, wherein the first sensing signal line is positioned on one side of the insulating layer and the second sensing signal line are positioned on the other side of the insulating layer; a sensing signal processor connected with the first and second sensing signal lines; a gate line transmitting a gate signal to a pixel, the gate line being positioned on the insulating layer, being adjacent to and substantially parallel to the first sensing signal line, wherein the sensing signal processor determines whether an external object contacts on the first surface based on a voltage difference of the sensing capacitor, wherein one of the first and second sensing signal lines transmits a sensing input signal to charge the sensing capacitor, and the other one of the first and second sensing signal lines transmits a sensing output signal from the sensing capacitor, and wherein the first sensing signal line directly contacts the first sensing electrode everywhere the first sensing signal line overlaps the first sensing electrode, and wherein at least of the first sensing electrode and the second sensing electrode includes a thinner portion, and only the thinner portion overlaps the gate line in a display area.
