본 개시의 실시예들은, 액티브 영역의 제1 서브 영역과 제2 서브 영역에 터치 전극이 분리되어 배치된 구조에서, 제1 서브 영역과 제2 서브 영역에 배치된 X-터치 전극은 서로 전기적으로 연결되고 Y-터치 전극은 서로 전기적으로 분리된 터치 디스플레이 장치를 제공할 수 있다. 서브 영역 별로 터치 전극이 분리된 구조에 의해 로드를 감소시키며, 제1 서브 영역과 제2 서브 영역의 X-터치 전극을 동일한 채널로 구동하여 채널 수를 감소시킬 수 있다. Embodiments of the disclosure may provide a touch display device in which in a structure in which touch electrodes are separately disposed in a first sub area and a second sub area of an active area, X-touch electrodes disposed in the first sub area and the second sub area are electrically connected with each other, and Y-touch electrodes are electrically separated from each other. It is possible to reduce the load by a structure in which touch electrodes are divided for each sub area and to reduce the number of channels by driving the X-touch electrodes in the first sub area and second sub area by the same number of channels.
