Abstract:
1. A touch panel comprising: a first electrode plate comprising a first substrate and a first conductive layer located on a lower surface of the first substrate; and a second electrode plate separated from the first electrode plat; and comprising a second substrate and a second conductive layer located on an upper surface of the second substrate; wherein at least one of the first conductive layer and the second conductive layer comprises at least two stacked carbon nanotube layers, each of the at least two directly stacked carbon nanotube layers comprises a plurality of unfunctionalized carbon nanotubes aligned in a single direction, and the unfunctionalized carbon nanotubes in two adjacent carbon nanotube layers are aligned in different directions, each of the at least two directly stacked carbon nanotube layers comprises at least one carbon nanotube film, and the at least one carbon nanotube film comprises a plurality of successively oriented carbon nanotube segments joined end to end by van der Waals attractive force therebetween.
