The present invention provides a touch display panel. The substrate includes a display region and a non-display region. The first conductive pads, the second conductive pads, the first conductive lines and the second conductive lines are disposed in the non-display region. The first conductive lines are electrically connected to the first conductive pads and the sub-pixels in the display region. The second conductive lines are electrically connected to the second conductive pads and the touch electrodes in the display region. The second conductive line includes a first line segment, a second line segment and a third line segment. The first line segment extends in a first direction and is connected to the second conductive pad. The second line segment extends from the non-display region to the display region. The third line segment extends in a second direction and is connected to the first line segment and the second line segment.
