Abstract
A capacitance-type touch panel includes an insulating layer, a first transparent conductive layer, a number of first electrodes, a second transparent conductive layer, and at least one second electrode. The first transparent conductive layer includes a carbon nanotube film. The carbon nanotube film includes a number of carbon nanotube wires substantially parallel with each other and a number of carbon nanotube clusters located between the number of carbon nanotube wires. The carbon nanotube wires extend along an X direction and are spaced from each other along a Y direction. The carbon nanotube clusters between each adjacent two of the carbon nanotube wires are spaced from each other along the X direction. The X direction is intercrossed with the Y direction.
