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.

Abstract: Embodiments of the present disclosure are related to a touch display device, as a touch insulating film positioned under a touch electrode has a step difference and the touch electrode is disposed along a surface of the touch insulating film having the step difference. Thus, an area of the touch electrode disposed on an identical region increases and touch sensitivity can be improved. Furthermore, since the touch electrode is positioned lower toward from a central portion to an outer portion, a structure of the touch electrode being capable of improving touch sensitivity can be implemented without reducing a viewing angle of a light emitted from a light-emitting element positioned under the touch electrode.

Abstract: A touch display device is disclosed. Since a touch electrode line included in the display device is divided into two or more touch electrode line parts connected to different touch routing lines, an entire load of the touch electrode line and the touch routing line can be reduced. As a portion of the touch routing line is disposed on an active area and touch routing lines connected to different touch electrode line parts are connected to each other between the active area and a touch driving circuit, an entire load can be reduced without an increase of a non-active area and an increase of a channel due to the touch routing lines, and a performance of a touch sensing can be improved.

Abstract: A display device and a method of fabricating the same. An active area having pixels defined therein is provided on a substrate. A pad area is provided on the substrate to receive signals to be transferred to the active area. A wiring area is provided on the substrate, with electrical lines being disposed therein to connect the active area and the pad area. An inorganic film is disposed in the active area and the wiring area, with a thickness of the inorganic film, located in the wiring area, is lower than a thickness of the inorganic film, located in the active area. Electrical lines are prevented from being broken in a bendable structure intended for a narrow bezel.
