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: The present disclosure is directed to a touch display device that is capable of reducing a load of a touch sensor structure disposed in a display panel and improving the accuracy of touch sensing capabilities of the touch display device. In one aspect, touch electrode lines disposed on an active area are disposed to be separated into a plurality of sub-areas. A number of touch routing lines connected to the touch electrode lines are disposed on the active area, thus a touch sensor structure with a reduced load can be provided while minimizing an increase of a non-active area due to an arrangement of the touch routing lines.

Abstract: Disclosed is a display device having a reduced bezel area. The display device includes a plurality of touch lines electrically connected to a plurality of touch electrodes and display link lines electrically connected to a light-emitting element, the display link lines being disposed in a non-active area of a substrate, wherein a minimum of M touch lines (M being a natural number greater than 1 and less than N) is disposed with respect to a minimum of N display link lines (N being a natural number greater than 1), among the plurality of display link lines, in the non-active area. Consequently, a narrow bezel may be realized.
