1. A method for making a liquid crystal display screen, the method comprising steps of:

  • preparing a touch panel comprising a first and second carbon nanotube layers, the first carbon nanotube layer comprising of at least a first carbon nanotube film, the second carbon nanotube layer comprising of at least a second carbon nanotube film and a thin film transistor panel comprising a plurality of thin film transistors;

    wherein at least one of the first and second carbon nanotube films is treated with an organic solvent;

    applying a first polarizer on a surface of the touch panel; and

    placing a liquid crystal layer between the first polarizer and the plurality of thin film transistors;

    wherein the touch panel is prepared by the following steps of;

    forming a first and a second electrode plate, wherein forming the first electrode plate comprises;

    supplying a first substrate;

    laying the at least a first carbon nanotube film on the first substrate thereby forming a first conductive layer on the first substrate; and

    connecting two first electrodes to the first conductive layer; and

    forming the second electrode plate comprises;

    supplying a second substrate;

    laying the at least a second carbon nanotube film on the second substrate thereby forming a second conductive layer on the first substrate; and

    connecting two second electrodes to the second conductive layer; and

    assembling the first electrode plate and the second electrode plate together having a space between the first substrate and the second substrate.
