The present disclosure provides a touch substrate, a touch panel and a touch display device. The touch substrate includes a first electrode extending in a first direction. The first electrode is of a U shape, and includes a first longitudinal portion extending in the first direction, a second longitudinal portion extending in the first direction, and a third connecting portion. The first longitudinal portion includes a first terminal at an distal end from the connecting portion, and the second longitudinal portion includes a second terminal at an distal end from the connecting portion. In the touch substrate, the first and second electrodes are powered from both ends. The metal wirings connecting the electrodes to the bonding pins do not cross.
