When the surface of the liquid crystal layer 338 is formed, a plurality of parallel and uniformly distributed trenches are formed on the surfaces of the first fixed layer 304b and the second fixed layer 324b; the trench may be used as the first alignment layer 304 and the second alignment layer 324. The first trench 308 and the second trench 328. ❹ When the materials of the first fixed layer 304b and the second fixed layer 324b are diamond-like hydride, nitrite, amorphous hydride, carbonized carbide, cerium oxide, aluminum oxide, cerium oxide, oxidation When tin, zinc titanate or indium titanate is used, it may be attached to the first nano tube layer 304a and the second nano tube layer 324a by evaporation, sputtering or plasma enhanced chemical vapor deposition (PECVD) growth. s surface. When the material of the first fixing layer 304b and the second fixing layer 324b is polyvinyl alcohol, polyimine, polymethyl methacrylate or polycarbonate, the first coating can be attached to the first naphthalene by a silicone method. The surface of the carbon nanotube layer 304a and the second carbon nanotube layer 324a. The first fixed layer 304b and the second fixed layer 324b have a thickness of 20 nm to 2 μm. The first carbon nanotube layer 304a is identical in structure to the second carbon nanotube layer 324a. Hereinafter, only the first carbon nanotube layer 304a will be described as an example. The first carbon nanotube layer 304a includes a plurality of carbon nanotube long lines 310 arranged in parallel and closely arranged. Referring to FIG. 5, the carbon nanotube long line 310 includes a bundle structure consisting of a plurality of end-to-end connected carbon nanotube bundles in parallel or a twisted pair of a plurality of end-to-end connected carbon nanotube bundles twisted to each other. 200947071 structure. The adjacent carbon nanotube bundles are tightly bonded by a van der Waals force, and the bundle of carbon nanotubes includes a plurality of end-to-end aligned carbon nanotubes. The diameter of the long carbon nanotube 310 is i nanometers to 1 micrometer, and the length thereof is not limited. Between the long lines of the carbon nanotubes, there are a plurality of parallel and evenly distributed gaps between the carbon nanotube bundles in the long carbon nanotubes 310 and between the carbon nanotubes. The carbon nanotubes in the long carbon nanotube 310 of the carbon nanotubes include one or more of a single-walled carbon nanotube tube, a double-walled carbon nanotube, and a multi-walled carbon nanotube. The diameter of the single-walled carbon nanotube is 0.5 Ny to 1 〇 nanometer, the diameter of the double-walled carbon nanotube is 1.0 nm to 15 nm, and the diameter of the multi-walled carbon tube is 15 nm~ 50 nm. In this embodiment, the first carbon nanotube layer 3〇4a and the second carbon nanotube layer 324a respectively comprise a plurality of parallel and closely arranged carbon nanotube long lines, and the first carbon nanotube layer 304a The extension direction of the long carbon wire 31〇 of the carbon nanotube is perpendicular to the direction of the extension of the long carbon wire 32〇 of the second carbon nanotube layer 324a, so that the first groove of the first alignment layer 3〇4 The extending direction of the second trench 328 of the 3 〇 8 disk second alignment layer 324 is perpendicular to align the liquid crystal molecules in the liquid crystal layer 338. Specifically, the first trench 308 in the first alignment layer extends in the X-axis direction, and the plurality of first trenches & 3〇8 are arranged in parallel; the second trench 328 in the second alignment layer 324 is along the 2 axis 3 The direction extends and a plurality of second trenches 328 are arranged in parallel. The thickness of the first alignment layer 304 and the second alignment layer 324 ranges from (10) m to 5 μm, respectively. In addition, since the first carbon nanotube layer 304 & and the second carbon nanotube 13 .200947071 layer 324a respectively comprise a plurality of parallel and closely arranged carbon nanotubes. Long lines, and the carbon nanotube long line The utility model comprises a plurality of carbon nanotubes which are connected end to end and oriented, so that the carbon nanotube layer has good electrical conductivity and can serve as a transparent electrode layer and at the same time function as an alignment layer. Therefore, when the liquid crystal display panel 300 of the embodiment adopts an alignment layer containing a carbon nanotube layer, there is no need to additionally add a transparent electrode layer, thereby making the liquid crystal display screen have a thin thickness, simplifying the structure and manufacture of the liquid crystal display panel. Cost, improve the utilization of high backlights, and improve display quality. In addition, the first carbon nanotube layer 304a and the second carbon nanotube layer 324a are disposed on the substrate without mechanical brushing or other processing to create a groove, which itself has a groove and does not generate static electricity. And dust, so that the liquid crystal display goo has better alignment quality. In addition, since the first carbon nanotube layer 3 and the second carbon nanotube layer 32 have better flexibility, the liquid crystal display panel 300 can be made into a flexible liquid crystal display. Further, the first fixed layer 304b and the second fixed layer 32 are respectively covered on the surfaces of the first carbon nanotube layer 304a and the second carbon nanotube layer 324a, so that the first carbon nanotube can be made. When the layer 304a and the second carbon nanotube layer 324a are in contact with the liquid crystal material for a long time, they do not fall off, so that the liquid crystal display panel 300 has a long service life and a good alignment quality. It can be understood that 'when the first fixed layer 304b and the second fixed layer 324b are not covered on the surfaces of the first carbon nanotube layer 304a and the second carbon nanotube layer 324a' due to the first carbon nanotube The layer 304a and the second carbon nanotube layer 324a are immersed in the liquid crystal material for a long period of time and are easily peeled off. The doping of the carbon nanotubes in the liquid crystal layer 338 causes the liquid crystal layer 338 to conduct electricity, short-circuiting the .200947071 alignment layer 304 and the second alignment layer 324, so that the liquid crystal display screen 300 does not work normally. The plurality of carbon nanotube layers 304a and the second carbon nanotube layer 324a are arranged in parallel, so the first carbon nanotube layer 304a and the second layer The carbon nanotube layer 324a has a polarizing effect on natural light, so that it can be polarized instead of the polarizing plate of the prior art. In order to make the liquid crystal display panel 300 have a better polarization effect, at least one polarizing plate (not shown) may be disposed on the surface of the first substrate 322 and/or the second substrate 302 away from the liquid crystal layer 338. Further, the liquid crystal display panel 300 further includes at least two extraction electrodes (not shown) electrically connected to the first carbon nanotube layer 304a and the second carbon nanotube layer 324a, respectively. The extraction electrode is used to apply a voltage between the first alignment layer 304 and the second alignment layer 324 of the liquid crystal display 300 such that liquid crystal molecules located between the first alignment layer 304 and the second alignment layer 324 are deflected. Q It can be understood that the liquid crystal display 300 illustrated in the technical solution is only a single pixel. Further, a plurality of the single-pixel liquid crystal display panels 300 may be arranged in a predetermined pattern, such as a dot matrix setting, for a liquid crystal display screen of a plurality of pixels. It can be understood that the liquid crystal display of the plurality of pixels can adopt the same basic large-area first substrate 302 and second substrate 322 by using a common substrate. Alternatively, a plurality of liquid crystal displays 300 may be directly assembled together without sharing the substrate. The working process of the liquid crystal display panel 300 of the present embodiment will be described below with reference to Figs. 6 and 7. 15.200947071 As shown in FIG. 6, when no voltage is applied between the first alignment layer 3〇4 and the first white layer 324, the alignment of the liquid crystal molecules is in accordance with the first alignment layer-304 and the second alignment layer 324. Depending on the orientation. In the liquid crystal display panel 300 of the embodiment, the alignment directions of the first alignment layer 304 and the second alignment layer 324 are formed at 90 degrees, so that the arrangement of the liquid crystal molecules in the liquid crystal layer 338 is automatically rotated by 90 degrees from top to bottom. . When the incident light [passes through the first alignment layer 304] is in the z-axis direction due to the transmission axis of the first alignment layer 3〇4, only the polarized light whose polarization direction is parallel to the transmission axis passes. When the polarized light L1 passes through the liquid crystal molecules, since the liquid crystal molecules are rotated in total, when the polarized light L1 reaches the second alignment layer 324, the polarization direction of the polarized light L1 is just rotated by 90 degrees. Since the transmission axis of the second alignment layer 324 is along the X-axis direction, that is, the polarization direction of the polarized light L1 is parallel to the transmission axis by turning 90 degrees, and thus can smoothly pass through the second alignment layer 324, at this time, The liquid crystal display panel 3 of the embodiment is in a light-passing state. As shown in FIG. 7, when a voltage is applied between the first alignment layer 304 and the second alignment layer 324, the liquid crystal molecules are affected by the electric field, and the alignment direction thereof tends to be parallel to the electric field direction and becomes the first substrate 3. 〇 2 vertical state. At this time, the polarized light Li passing through the first alignment layer 3〇4 does not change the polarization direction when passing through the liquid crystal molecules, so that the second alignment layer 324 cannot pass through, and the liquid crystal display panel 3 of the present embodiment is Shading state. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
