Abstract: Disclosed is a touch display device capable of reducing deterioration in touch performance. The touch display device includes a plurality of first touch electrodes disposed in an active area of a substrate and a plurality of second touch electrodes disposed in the active area of the substrate, the plurality of second touch electrodes having different shapes from the plurality of first touch electrodes, wherein at least one of the plurality of second touch electrodes is formed by connecting at least two sub-electrodes having smaller areas than each of the first touch electrodes to each other. Consequently, the areas of the first and second touch electrodes are similar to each other, whereby it is possible to reduce touch performance deteriorated due to deviation in area between the touch electrodes.

Abstract: A display apparatus is provided. In the display apparatus, a touch electrode may be disposed on the encapsulating element covering a light-emitting device, and a touch pad may be disposed on the outside of the encapsulating element. A touch line may be connected to the touch electrode. The touch line may be connected to the touch pad by a first touch link and a second touch link. The first touch link may include a first end connected to the second touch link, and a second end connected to the touch line. The first end of the first touch link may overlap with the encapsulating element. Thus, in the display apparatus, the reliability for a touch of a user or a tool may be improved.
