Description of the Invention: [Technical Field] The present invention relates to a touch screen and a display device using the same, and more particularly to a carbon nanotube-based touch screen and a touch screen using the same. [Prior Art] In recent years, with the development of various types of electronic devices such as mobile phones and touch navigation systems, the development of electronic devices having a translucent touch panel on the front side of display elements such as liquid crystals has been increasing. The user of such an electronic device visually confirms the display content of the display element located on the back surface of the touch panel through the touch panel, and presses the touch panel to operate by using a finger or a pen. Thereby, it is possible to operate various functions of electronic damage. According to the working principle of the touch screen and the transmission medium, the previous touch screens are generally divided into four types, namely resistive, capacitive sensing, infrared and surface acoustic waves. Among them, resistive touch screens are the most widely used. (K. Noda, K. Tanimura, Electronics and Communications in
