Abstract
A touch display device is disclosed. By making at least one of a thickness or an angle of inclination of an insulating layer disposed on an area where a touch routing line is disposed on a non-active area of a display panel and an area that lacks the touch routing line to be different from each other, a short circuit between touch routing lines due to a defect in a process arranging the touch routing lines can be reduced.
Claims18
A touch display device comprising:
- a plurality of light-emitting elements on an active area of a display panel;
- an encapsulation layer on the plurality of light-emitting elements;
- a first touch sensor metal on the encapsulation layer and comprising a plurality of touch electrodes and a plurality of touch routing lines electrically connected to the plurality of touch electrodes, the plurality of touch routing lines extending to a pad area positioned outside of the encapsulation layer;
- a planarization layer on the encapsulation layer, the planarization layer extending to an area between the active area and the pad area;
- a first touch insulating layer on the planarization layer;
- a second touch sensor metal on the first touch insulating layer and comprising a plurality of touch electrode connecting patterns and a plurality of auxiliary routing patterns;
- and
- a second touch insulating layer on the first touch insulating layer;
- wherein the first touch insulating layer includes an inorganic material and the second touch insulating layer includes an organic material, and
- wherein the second touch insulating layer covers the plurality of auxiliary routing patterns.
