Field of the Invention The present invention relates to a touch screen and a display device, and more particularly to a touch screen using a carbon nanotube as a transparent conductive layer and a display device using the touch screen. [Previous technology] "° 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 in front of liquid crystal display devices are gradually increase. The user of such an electronic smear uses the touch screen to visually confirm the display content of the display device located on the back surface of the touch panel, and presses the touch panel by a finger or a pen to operate. Therefore, various functions of the electronic device can be operated. According to the working principle of the touch screen and the transmission medium, the touch screens in the prior art are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic wave. Among them, the capacitive touch screen is widely used due to its high accuracy and strong anti-interference ability. Capacitive touch screens of the prior art (see "Study of Continuous Thin Tantalum Touch Touch Screens", Li Shuben et al., Optoelectronics, v. 1 6 962 (1995)) including a glass substrate 'a transparent conductive layer, and Multiple metal electrodes. In the capacitive touch panel, the material of the glass substrate is a nano-feed glass. The transparent conductive layer is a transparent material such as indium tin oxide (ITO) or antimony tin oxide (AT0). The electrode is formed by printing a conductive metal (e.g., silver) having a low electrical resistance. The electrode spacing is disposed at each corner of the transparent conductive layer. Further, the transparent conductive layer is coated with a protective layer. The protective layer is formed by a hardening or densification process of the liquid glass material and subjected to heat treatment and then hardened. When a touch object such as a finger touches the surface of the touch screen, due to the human body electric field, 200929636 forms a combined capacitance between the touch object such as a finger and the transparent conductive layer in the touch screen. For high-frequency currents, the capacitor is a direct conductor, and the touch of a finger or the like picks up a small current from the contact point. This current flows out of the electrodes on the touch screen, respectively, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The touch screen controller calculates the position of the touch point by accurately calculating the ratio of the four currents. Therefore, the transparent conductive layer is an essential component for the touch screen. In the prior art, the transparent conductive layer usually adopts an ITO layer. However, the ITO layer as a transparent conductive layer has disadvantages such as insufficient mechanical and chemical durability. Further, the use of the ITO layer as the transparent conductive layer has a phenomenon in which the resistance value distribution is uneven, resulting in the problem that the capacitive touch screen of the prior art has low resolution and low precision of the touch screen. In view of this, it is indeed necessary to provide a touch screen having high resolution, high precision, and durability, and a display device using the touch screen. SUMMARY OF THE INVENTION A touch screen includes a substrate, a transparent conductive layer disposed on a surface of the substrate, and two first electrodes and two ® second electrodes. Wherein, the transparent conductive layer comprises a plurality of carbon nanotube long lines respectively arranged in parallel in the first direction and the second direction, and the first direction intersects the second direction. The two ends of the long carbon nanotubes disposed along the first direction are electrically connected to the two first electrodes, respectively, and the two ends of the long carbon nanotubes disposed along the second direction are respectively electrically connected to the two second electrodes connection. A display device comprising a touch screen, the touch screen comprising a substrate; a transparent conductive layer disposed on a surface of the substrate; two first electrodes and two second electrodes; and a display device The display device is facing and close to the base of the touch screen. Wherein, the transparent conductive layer comprises a plurality of nanometers; and the second and second directions intersect with each other in the first direction and the second direction. The ~ direction disposed along the first direction is not electrically connected to the two first electrodes, and the second direction is disposed such that both ends of the long line are electrically connected to the two second electrodes, respectively. The anti-burst is compared with the prior art. The touch screen provided by the technical solution has the following advantages: one is because the plurality of nano-eyes in the transparent conductive layer are interlaced or overlapped and cross-connected, so the transparent conductive The layer has the mechanical properties of ^, , ', so that the above transparent conductive layer has better mechanical 3 and toughness. Therefore, using the above-mentioned nano carbon tube long line as a transparent conductive layer can comprehensively improve the durability of the touch screen. , thereby increasing the durability of the display using the touch screen. Secondly, a plurality of carbon nanotubes in the transparent conductive layer are arranged in a long line and spaced apart, so that the transparent conductive layer has a uniform resistance distribution and light transmittance, thereby improving the resolution of the touch screen and the display device using the touch screen.
