Abstract: A display device can include an optical electronic device disposed in a display area. To address a reduction of sensitivity of a touch panel disposed in a first sub-display area of the display area in which the optical electronic is disposed, an edge of a touch electrode in the first sub-display area can be provided with a finger part, a size of the touch electrode in the first sub-display area can be reduced, or a sub-touch electrode can be connected to the touch electrode in the first sub-display area, thereby increasing sensing sensitivity of the touch electrode.

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.
