Abstract: A display panel and a touch display device are disclosed. The display panel includes a first touch electrode positioned in the first area, a second touch electrode positioned in the second area, a third touch electrode positioned in the third area, a fourth touch electrode positioned in the fourth area, and a first connection pattern electrically connecting the first touch electrode and the second touch electrode. A connection portion between the third touch electrode and the fourth touch electrode may pass through an intermediate area between the first area and the second area. The first connection pattern may pass through the intermediate area between the first area and the second area and may cross the connection portion between the third and fourth touch electrodes. Each of the first, second, third and fourth touch electrodes may include a first metal layer and a second metal layer, the first metal layer and the second metal layer may be separated by a touch-interlayer insulating layer. The first connection pattern may be disposed on one of the first metal layer and the second metal layer. The first connection pattern may be located in one of the first metal layer and the second metal layer.
