Abstract
A touch panel includes a first electrode plate, and a second electrode plate separated from the first electrode plate. The first electrode plate includes a first substrate and a first conductive layer located on a lower surface of the first substrate. The second electrode plate includes a second substrate and a second conductive layer located on an upper surface of the second substrate. At least one of the first conductive layer and the second conductive layer includes a carbon nanotube layer. The carbon nanotubes in the carbon nanotube layer form a carbon nanotube floccule structure.
