Embodiments of the present disclosure are related to a touch display device, as disposing a plurality of touch pads located on a plurality of lines alternatively and making a metal other than the touch pad not to expose to outside, the number of the touch pads being capable of disposing on a pad area can be increased and a reliability of the touch pad can be maintained. Furthermore, as disposing pad lines, electrically connected to the touch pad and located adjacently, on different layers, a short between adjacent pad lines can be prevented and a space between the touch pads can be reduced or minimized, a disposition structure of the touch pad can be implemented easily according to increasing the number of channels in a large size of the touch display device.

Touch display device

An organic light-emitting display device includes an anti-peeling pattern. An organic light-emitting element including a pixel electrode, an organic light-emitting layer, and a common electrode is disposed on a substrate. A bank layer is disposed on the pixel electrode so as to expose at least a portion of the pixel electrode. The anti-peeling pattern having at least one delta-shaped space is disposed on the bank layer. The anti-peeling pattern, disposed on the bank layer, minimizes peeling of the encapsulation layer that can be caused by either compressive or tensile stress generated by bending in a flexing environment in which the organic light-emitting display device is used.

Organic light-emitting display device

A touch display device includes a touch planarization film. The touch planarization film may be disposed on an inclined portion of an encapsulation layer in a non-active area of a display panel, and a touch routing line may be disposed on the planarized area of the touch planarization film, so that it is possible to reduce parasitic capacitance between the touch routing line and a display signal line located under the encapsulation layer without increasing dimensions of the non-active area. Therefore, it is possible to easily adjust a width of the touch routing line and reduce the parasitic capacitance deviation between the touch routing lines, thereby improving the performance of the touch sensing.

This present disclosure discloses a display device. The display device may include a bending area and a non-bending area. A structure for improving durability may be included in the bending area. The display device may include a base layer having one or more first regions that can be folded along a predetermined axis, and a second region adjacent to the first regions; and thin-film transistors, organic light-emitting elements and functional layers stacked in the second region of the base layer. The thin-film transistors, the organic light-emitting elements and the functional layers stacked in the second regions are not disposed in the first regions. Instead, the space otherwise occupied by the elements is filled with the filling layer.
