Abstract
A touch panel includes a substrate, a transparent conductive layer, and at least two electrodes. The transparent conductive layer is formed on a surface of the substrate. The transparent conductive layer includes at least two carbon nanotube layers, and each carbon nanotube layer includes a plurality of carbon nanotubes arranged along a same direction. The carbon nanotubes of adjacent carbon nanotube layers are arranged along different directions. The electrodes are electrically connected with the transparent conductive layer. Further, a display device using the touch panel is also included.
