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 display device using the same. [Prior Art] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a translucent touch panel is mounted on the front surface of a display element such as a liquid crystal are gradually increasing. The user of such an electronic device operates by pressing the touch panel by a finger, a pen, or the like while visually checking the display content of the display element located on the back surface of the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. 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 wave. Among them, the resistive touch screen is the most widely used. Please refer to the document "Production of Transparent Conductive Films with Inserted Si02 Anchor Layer, and Application to a Resistive Touch Panel,> Kazuhiro Noda, Kohtaro Tanimura. Electronics and Communications in Japan. , Part 2, Vol. 84, P39-45 (2001) ° The prior resistive touch screen generally comprises an upper substrate, the upper surface of which is formed with an upper transparent conductive layer; the lower substrate, the upper surface of which is formed with a transparent conductive layer; and a plurality of dot spacers (Dot 8 201003487

In addition, the ribs gradually decrease in transparency in the wet layer 7. Leading to the previous resistive touch screen, the device has the disadvantages of insufficient durability, low sensitivity, poor linearity and accurate car. In addition, the 'previous resistive touch screen can only achieve single-point input signal.
