[Prior Art] [0002] The liquid crystal alignment technology is one of the key technologies for determining the quality of a liquid crystal display, because the quality of the liquid crystal alignment technology directly affects the quality of the final liquid crystal display. The liquid crystal display of the southern enamel requires a stable and uniform initial alignment of the liquid crystal, and a thin layer having an effect of inducing alignment of the liquid crystal is called a liquid crystal alignment layer. [0003] The alignment layer materials used in the prior art for liquid crystal display panels are polystyrene and its derivatives, polyimine, polyvinyl alcohol, polyester, epoxy resin, polyurethane, polydecane, etc., the most common It is a polyimine. These materials are subjected to film rubbing, oblique vapor deposition of Si〇x film method and microchannel treatment of the film (see "Atomic-beam alignment of inorganic materials for liquid-crystal displays", P. Chaudhari, et al. After treatment by Nature, vol 411, p56 (200 1 )), etc., a plurality of trenches can be formed which can align the liquid crystal molecules. [0004]. Referring to the liquid crystal display 100 shown in FIG. 1, the first substrate 104, the second substrate 112, and the liquid crystal layer 118 sandwiched between the first substrate 104 and the second substrate 112 are included.

The second alignment layer 116 is formed with a plurality of second trenches 1162 parallel to each other near the surface of the liquid crystal layer 118. The arrangement direction of the first trenches 1 082 and the second trenches 1162 is perpendicular to each other, so that the liquid crystal molecules 1182 in the liquid crystal layer 118 can be oriented even if they are close to the first trenches 1082 and the second trenches 1162. The liquid crystal molecules 1182 are aligned along the direction of the first trench 1082 and the second trench 1162, respectively. Thereby, the arrangement of the liquid crystal molecules 1182 is automatically rotated by 9 degrees from top to bottom.

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 has the same structure as the second carbon nanotube layer 324a. The following description will be made by taking only the first carbon nanotube layer 304a as an example. The first carbon nanotube layer 304a includes a plurality of parallel and closely arranged carbon nanotube long lines 310. Referring to FIG. 5, the carbon nanotube long line 310 includes a bundle structure consisting of a plurality of end-to-end carbon nanotube bundles in parallel or a plurality of The end-to-end connected carbon nanotube bundles are twisted to each other to form a twisted wire structure. The adjacent carbon nanotubes are bundled between the van der Waals force and tightly 09117720 (P number A0101 page 9 / total 24 pages 1013147820-0 1377415 101 Year. April 20th revised replacement page combination, the carbon nanotube bundle includes a plurality of head and tail And aligned carbon nanotubes. The diameter of the long carbon nanotube 310 is from 1 nm to 100 μm, and the length thereof is not limited. The carbon nanotube long line 310, the carbon nanotube long line 310 There are a plurality of parallel and evenly distributed gaps between the carbon nanotube bundles in the middle and the carbon nanotubes. [0018] The carbon nanotubes in the long carbon nanotubes 310 of the carbon nanotubes comprise single-walled carbon nanotubes, One or more of double-walled carbon nanotubes and multi-walled carbon nanotubes. The diameter of the multi-walled carbon nanotubes is 1. 5 nanometers to 15 nanometers, and the diameter of the multi-walled carbon nanotubes is 1. 5 Nai _ seeking ~ 5 0 nano. [0019] In this embodiment, the first carbon nanotube layer 304a 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 The extending direction of the carbon nanotube long line 310 of 304a is perpendicular to the extending direction of the carbon nanotube long line 320 of the second carbon nanotube layer 324a, thereby causing the first trench 308 and the second of the first alignment layer 304. The extending direction of the second trench 328 of the 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 304 extends in the X-axis direction, and the plurality of first trenches 308 are arranged in parallel; the second trench 328 in the second alignment layer 324 extends in the Z-axis direction. 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 1 micrometer to 50 micrometers, respectively. [0020] In addition, since the first carbon nanotube layer 304a and the second carbon nanotube layer 324a respectively comprise a plurality of long and closely arranged carbon nanotube long lines, and the carbon nanotube long line includes a plurality The carbon nanotubes are connected end to end and oriented, so that the carbon nanotube layer has good electrical conductivity 1013147820-0. 101.04.04.20 revised replacement page, which can be used as a transparent electrode layer and a material alignment layer Play a matching role. Therefore, when the liquid crystal display panel 3 of the present embodiment adopts an alignment layer containing a carbon nanotube, there is no need to additionally add a transparent electrode layer, so that the liquid crystal display panel 300 has a thin thickness, simplifying the liquid crystal display. Structure and manufacturing cost, h asks for the utilization of the light source and improves the display quality. In addition, the first carbon nanotube layer 304a and the second carbon nanotube layer 324a are disposed on the substrate and do not need to be mechanically brushed or otherwise processed to create a trench, which itself has (4) 'will not generate static electricity and Dust, so that the liquid crystal display 300 has a better alignment quality. In addition, since the first carbon s-layer 304a and the second naphtha 324a have good flexibility, the liquid crystal display can be made into a flexible liquid crystal display. Further, covering the first fixed layer 3〇4b and the second fixed layer 3241> respectively, the surface of the first carbon nanotube layer 304a and the second carbon nanotube layer 324a may make the first nanocarbon When the tube layer a 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 cover the surface of the first carbon nanotube layer 304a and the second carbon nanotube layer 324a, due to the first carbon nanotube The layer 3043 and the second carbon nanotube layer 324a are immersed in the liquid crystal material for a long 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 second alignment layer 3〇4 and the second alignment layer 324, so that the liquid crystal display is not working properly. The plurality of carbon nanotube long lines in the first carbon nanotube layer 304a and the second carbon nanotube layer 324a are arranged in parallel, so the first carbon nanotube A0101 is 11 pages/total 24 pages 1013147820-0 1377415 101 〇 April 20th Amendment Replacement Page [0023] [0025] [0026] Layer 304a and second carbon nanotube layer 324a have a polarization effect on natural light' and thus can replace the prior art The polarizer acts as a polarizer. 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, so that liquid crystal molecules located between the first alignment layer 304 and the second alignment layer 324 are deflected. It is 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 3 can 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 3〇2 and second substrate 322 by using a common substrate. Alternatively, a plurality of liquid crystal displays 3 can be directly assembled together without sharing the substrate. The operation of the liquid crystal display panel 300 of the present embodiment will be described below with reference to Figs. 6 and 7. As shown in Fig. 6, when no voltage is applied between the first alignment layer 3〇4 and the second alignment layer 324, the alignment of the liquid crystal molecules depends on the alignment of the first alignment layer 304 and the second alignment layer 324. In the liquid crystal display panel 300 of the present embodiment, the alignment of the first alignment layer 304 and the second alignment layer 324 is 09117720 (f. single number A01〇l page 12/24 pages 1013147820-0 1377415 |" On April 20, 1st, the shuttle is formed 90 degrees in the forward direction. Therefore, 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 L passes through the first alignment layer 304, The transmission axis of the alignment layer 304 is along the Z-axis direction, so that only the polarization L1 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 by 90 degrees in total, when When the polarized light L1 reaches the second alignment layer 324, the polarization direction of the polarized light L1 is exactly 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 rotated by 90. The degree is parallel to the transmission axis, so that the second alignment layer 324 can be smoothly passed. At this time, the φ liquid crystal display panel 300 of the present embodiment is in a light-passing state. [00^7] As shown in FIG. When a voltage is applied between the first alignment layer 304 and the second alignment zan 324, the liquid crystal molecules The influence of the electric field tends to be parallel to the direction of the electric field and becomes perpendicular to the first substrate 302. At this time, the polarized light L1 passing through the first alignment layer 304 does not change the polarization direction when passing through the liquid crystal molecules, so The second alignment layer 324 cannot be passed. At this time, the liquid crystal display panel 300 of the embodiment is in a light-shielded state. j-〇〇28] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law.
