Description of the invention: · [Technical field to which the invention pertains] I The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display that can operate at low temperatures. [Prior Art] Liquid crystal display is one of the best display modes because of low power consumption, miniaturization, and high-quality display. LCD display is the best display method due to low power consumption, miniaturization and high-quality display (see ❹ Atomic-beam alignment of inorganic materials for liquid-crystal displays), P. Chaudhari, et al., Nature , vol 411, p56 (2〇01)). The more commonly used liquid crystal display is TN (Twisted Nematic) liquid crystal display (TN-LCD). For TN-LCD, no voltage is applied to the electrode. When the LCD screen is in the "OFF" state, the light energy is transmitted through the liquid crystal display; when a certain voltage is applied to the electrodes, the liquid crystal display is in the "ON" state, and the long-axis direction of the liquid crystal molecules is arranged along the direction of the electric field. Light can't pass through the liquid crystal display, so it is in a light-shielding state. Selectively applying a voltage on the electrode can display different patterns. However, the low-temperature operating characteristics of the liquid crystal display in the prior art are relatively poor, which greatly hinders the The use of liquid crystal display in low temperature environment. The main reasons for the LCD screen not working properly at low temperature are as follows: First, the field value of the LCD screen As a function of the temperature of the voltage system, as the temperature decreases, the voltage of the domain value increases. Therefore, the change of the voltage of the domain value causes the contrast to deteriorate. The second liquid crystal display is based on the change of the state of the liquid crystal molecules to realize the display function. At room temperature, the process of changing the liquid crystal molecules is a molecular process, and its response speed is much slower than that of the atomic process, the electricity process, and the process of the rise or fall is a The process of changing the state of the liquid crystal molecules with the resistance. As the ambient temperature decreases, the viscosity of the liquid crystal molecules increases, and the resistance of the liquid crystal molecules changes: the response speed becomes slower. Therefore, how It is a research hotspot to make the liquid crystal display work normally at low temperature. The first technique uses a heating layer on the inner side or the outer side of the liquid crystal display substrate to compensate the temperature of the liquid crystal display, so that the liquid crystal display works at a low temperature. The material of the heating layer is usually made of indium tin oxide transparent conductive film. However, due to indium tin oxide transparent conductive 臈The coupling resistance is small and the heating performance is not ideal, so the liquid crystal display panel using the above heating layer cannot effectively improve the low temperature display effect. In view of this, it is necessary to provide a liquid crystal display panel which can work at a low temperature. a first substrate; a second substrate, the first substrate is disposed opposite to the second substrate; a liquid crystal layer disposed between the first substrate and the first substrate; - a first conductive alignment layer a surface disposed on the surface of the first substrate and the first conductive alignment layer adjacent to the surface of the liquid crystal layer; the first trench; and a second conductive alignment layer disposed on the substrate a surface of the liquid crystal layer, and the surface of the second conductive alignment layer adjacent to the liquid helium layer includes a plurality of parallel second trenches, and the second trench alignment direction of the second conductive alignment layer is aligned with the first conductive alignment The first trench is arranged vertically, wherein the liquid crystal display further comprises at least one transparent heating layer. The transparent heating layer is disposed on the first substrate or/and the second substrate. Surface, and the transparent layer comprises a plurality of carbon nanotube heating. Compared with the prior art, the liquid crystal display has the following advantages: First, the first substrate or/and the second substrate can be heated by providing at least one transparent heating layer, so that the liquid crystal display can be at a low temperature Work under. Secondly, since the transparent heating layer is disposed on the outer side of the first substrate or/and the second substrate, the liquid crystal display can be operated at a low temperature without changing the internal structure and the optical path of the original liquid crystal display. .
