TOUCH SCREEN-INTEGRATED DISPLAY DEVICE
First Claim
1. A display device having an active area, a non-active area, and a pluarality of subpixels at the active area, comprising:
- a gate line and a data line to define a subpixel;
a thin-film transistor in the subpixels;
a passivation layer on the thin-film transistor and having an opening area in the non-active area where the passivation layer is removed;
a signal supply pad in the opening area;
a line pad in the opening area and on a first protective layer covering the signal supply pad;
a pad connection layer connecting the line pad through at least one first contact hole and the signal supply pad through at least one second contact hole in the opening area;
a first electrode on the passivation layer and connected to a source electrode of the thin-film transistor through a fourth contact hole, and the first protective layer on the first electrode;
a second electrode on a second protective layer and overlapping the first electrode; and
a touch sensing line in parallel with the data line.

Abstract
There is provided a touch screen-integrated display device. The touch screen-integrated display device includes: a substrate including an active area including a plurality of subpixels and a non-active area; a gate line and a data line to define one subpixel; a thin-film transistor disposed in subpixel; a first electrode electrically connected to a source electrode of the thin-film transistor; and a second electrode disposed to be overlapped with the first electrode with a protective layer interposed therebetween, and further includes a pad connection layer configured to connect the line pad and the signal supply pad in the non-active area. Thus, it is possible to reduce a contact resistance between the signal supply pad and the line pad and also possible to suppress damage to the pad connection layer.
