A touch panel includes a substrate, first electrodes, second electrodes, third electrodes, and fourth electrodes. The substrate includes a first touch region, a second touch region, and a first touch folding region disposed between the first touch region and the second touch region. The first electrodes extending from the first touch region to the first touch folding region and the second electrodes are disposed in the first touch region on the substrate. The third electrodes extending from the second touch region to the first touch folding region and the fourth electrodes are disposed in the second touch region on the substrate. The first electrodes and the third electrodes are not intersected with one another. A ratio of any side length of the touch panel to a distance between the first touch region and the second touch region is between 9.5 and 95.
