An exemplary touch panel includes a flexible substrate, a transparent conductive layer, and four electrodes. The flexible substrate includes a surface. The transparent conductive layer is disposed on the surface of the substrate. The transparent conductive layer includes a carbon nanotube layer. The carbon nanotube layer includes carbon nanotubes. The electrodes are separately disposed, and electrically connected with the transparent conductive layer. A display device using the above-described touch panel is also provided.
