Abstract: 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.

Abstract: 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.

Abstract: An organic light-emitting display device can include a flexible substrate, pixels disposed on the flexible substrate, each including a transistor connected to a pixel electrode and including a semiconductor layer, a gate electrode and source and drain electrodes, a planarization layer on the source and drain electrodes, a bank on a pixel electrode. Also, the organic light-emitting display device can include a first pair of protrusions on a first portion of an upper surface of the bank, a second pair of protrusions on a second portion of the upper surface of the bank, and a spacer between the first and second pair of protrusions. Further, a length of the first pair of protrusions at which the first pair of protrusions are disposed on the bank is different from that of the second pair of protrusions at which the second pair of protrusions are disposed on the bank.

Abstract: 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.
