1. A personal digital assistant, comprising:
- a body comprising a display screen; and
a touch panel located on a surface of the display screen, the touch panel being a resistance-type touch panel, and comprising;
a first electrode plate comprising;
a first substrate, a first transparent conductive layer located on a first surface of the first substrate, the first transparent conductive layer comprising a plurality of carbon nanotubes, which are arranged primarily along a first direction, andtwo first electrodes that are connected to the first transparent conductive layer; and
a second electrode plate separated from the first electrode plate, and comprising;
a second substrate located adjacent to the display screen;
a second transparent conductive layer located on the second substrate opposite to the first surface;
the second transparent conductive layer comprising a plurality of carbon nanotubes, which are arranged primarily along a second direction, the first direction being perpendicular to the second direction; and
two second electrodes that are electrically connected to the second transparent conductive layer.
