The thin layer 21 of the nano tube includes a carbon terrarium 212 aligned on the first substrate 2〇2 along the X-axis direction. The carbon nanotube 212 may be a single-walled carbon nanotube (SWNT), a multi-walled b (_), a single-walled carbon nanotube bundle (a carbon nanotube bundle) (hidden or super-aligned multi-wall carbon) Nano-tube long line (Super-al igned MTOT Yam illusion V〇1· 419, PP. 8G1, certificate), etc. The thickness of the first layer of nano-tubes 210: different from the carbon nanotubes, for example When a single-walled single-walled carbon nanotube is used, the thickness of the official layer is about 1 nm. When using a multi-wall carbon nanotube, = too t-meter, multi-wall carbon nanotube bundle or When the super-aligned multi-wall carbon nanotubes are long, the thickness of the first official thin layer 210 will gradually increase to several micrometers respectively. The plurality of barrier nanotubes 212 can be in the X-axis direction with the first substrate 2G2. The width is the same, and a length smaller than the twist can also be used. 7 Since the carbon nano-212 is a circular tube, a micro-groove 214 can be formed between each adjacent two carbon nanotubes 2丨2 ( Referring to FIG. 3), the first carbon nanotube thin layer 21〇 has an alignment effect on the liquid crystal molecules 240. The structure and function of the second carbon nanotube thin layer 228 and the first carbon nanotube The layer 21 is the same except that the carbon nanotubes 23 in the second carbon nanotube layer 228 are aligned on the second substrate 220 in the biaxial direction. The following is a combination of the third and fourth figures. The operation process of the invention of the liquid crystal display 2 is explained. As shown in the third figure, when no voltage is applied between the transparent electrodes 208 and 226, the arrangement of the liquid crystals 240 is in accordance with the thin layer of the carbon nanotubes 21, In the liquid crystal display 200 of the present invention, the alignment directions of the carbon nanotube thin layers 21, 228 are formed at 90 degrees, so that the arrangement of the liquid crystal molecules 240 is automatically rotated by 90 degrees from top to bottom. When the light ray 1 passes through the first polarizer 216, since the transmission axis 218 of the first polarizer 216 is along the X-axis direction, only the polarized light L1 whose polarization direction is parallel to the transmission axis 218 passes. When the polarized light L1 passes through the liquid crystal molecules 240, since the liquid crystal molecules 240 are rotated by 90 degrees in total, when the polarized light L1 reaches the second polarizer 234, the polarization direction of the polarized light L1 is just rotated by 90 degrees. The penetration axis 236 of the piece 234 is along the Z axis , Namely: li polarized polarization

At this time, the liquid crystal display 200 of the present invention is in a light-passing state. As shown in the fourth figure, when a voltage is applied between the transparent electrodes 208 and 226, the liquid crystal molecules 240 are affected by the electric field, and the arrangement direction thereof tends to be parallel to the direction of the electric field to become a standing state. At this time, when the polarized light L1 passing through the first polarizer 216 passes through the liquid crystal molecules 240, the polarization direction is not changed, so that the second polarizer 234 cannot be passed. At this time, the liquid crystal display 2 of the present invention is in a state of being shielded from light. Hereinafter, a method of manufacturing the liquid crystal display of the present invention will be described with reference to the second drawing. The manufacturing method of the liquid crystal display comprises the steps of: arranging the plurality of carbon nanotubes 212 in the z-axis direction on the inner surface of the first substrate 2〇2 by chemical vapor deposition growth, solution deposition or direct application.
