Abstract
An exemplary touch panel includes a substrate, transparent conductive layers, a capacitive sensing circuit, and conductive wires. The transparent conductive layers are disposed on a surface of the substrate and spaced apart from each other. Each transparent conductive layer includes a carbon nanotube layer. The carbon nanotube layer includes carbon nanotubes. The conductive wires respectively electrically connect the transparent conductive layers to the capacitive sensing circuit. A display device using the touch panel is also provided.
