向形成90度，所以液晶層338中的液晶分子的排列由上而 下會自動旋轉90度。當入射的光線L經過第一配向層304 時，由於第一配向層304的穿透軸沿Z轴方向，所以只有 偏振方向與穿透軸平行的偏振光L1通過。當偏振光L1通 過液晶分子時，由於液晶分子總共旋轉了 90度，所以當 偏振光L1到達第二配向層324時，偏振光L1的偏振方向恰 好轉了 90度。由於第二配向層324的穿透軸沿X軸方向， 即：偏振光L1的偏振方向因轉了 90度而與穿透軸平行， 從而可以順利的通過第二配向層324，此時，本實施例的 液晶顯示屏300處於通光的狀態。 [0023] 如圖7所示，當有電壓施加在第一配向層304和第二配向 097110186 表單編號A0101 第11頁/共23頁 1003435104-0 1356253 100年.11J Z3 日‘紐 層324之間時，液晶分子受電場的影響，其排列方向會傾

The liquid crystal display of the southern stem requires a stable and uniform initial alignment of the liquid crystal, and the thin layer having the effect of inducing alignment of the liquid crystal is called a liquid crystal alignment layer. The alignment layer materials known in the prior art for use in liquid crystal display screens include polyethylene and its derivatives, polyimine, polyvinyl alcohol, polyester, epoxy resin, polyurethane, polydecane, etc., the most common being poly Yttrium. These materials are subjected to a film rubbing method, a tilted vapor deposition SiO film method, and a microchannel treatment X method for a film (see "Atomic-beam alignment of inorganic materials for liquid-crystal displays", P. Chaudhari, et a 1. After treatment by a method such as Nature, vol 411, p56 (200 1 )), a plurality of trenches can be formed which can align the liquid crystal molecules. Referring to the liquid crystal display 100 shown in FIG. 1, a first substrate 104, a second substrate 112, and a liquid crystal layer 118 sandwiched between the first substrate 104 and the second substrate 112 are included. The first substrate 104 is disposed opposite to the second substrate 11 2 . The liquid crystal layer 118 includes a plurality of long rod-shaped liquid crystal molecules 1182.

The second alignment layer ι16 is formed near the surface of the liquid crystal layer 118 with a plurality of second trenches 1162 that are parallel to each other. The arrangement direction of the first trenches 1082 and the second trenches 1162 are perpendicular to each other, so that the liquid crystal molecules 1182 in the liquid crystal layer 118 can be aligned even if liquid crystal molecules are adjacent to the first trenches 1 082 and the second trenches 1162. 1182 are oriented along the direction of the first trench 1 082 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.

However, the presence of the above plurality of lamellar structures and their interfaces will increase the thickness, complexity, and manufacturing cost of the liquid crystal display panel, reducing the transmittance of light provided by the backlight and affecting the display quality. In view of this, it is necessary to provide a liquid crystal display having a simple structure, a thin thickness, and a better alignment quality.

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. [0021] The operation of the liquid crystal display panel 300 of the present embodiment will be described below with reference to FIGS. 6 and 7. [0022] As shown in FIG. 6, when no voltage is applied between the first alignment layer 304 and the second alignment layer 324, the alignment of the liquid crystal molecules is determined according to 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 directions of the first alignment layer 304 and the second alignment layer 324 are formed at 90 degrees, so 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, since the transmission axis of the first alignment layer 304 is along the Z-axis direction, 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 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 polarization L1 is parallel to the transmission axis by 90 degrees, the second alignment layer 324 can be smoothly passed. The liquid crystal display panel 300 of the embodiment is in a light-passing state. [0023] As shown in FIG. 7, when a voltage is applied between the first alignment layer 304 and the second alignment 097110186 Form No. A0101 Page 11 / Total 23 Page 1003435104-0 1356253 100 years. 11J Z3 Day 'New Layer 324 When the liquid crystal molecules are affected by the electric field, the alignment direction thereof 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 polarization when passing through the liquid crystal molecules. The direction is therefore unable to pass through the second alignment layer 324, and the liquid crystal display panel 300 of the present embodiment is in a light-shielded state. [24] The liquid crystal display panel 300 has the following advantages: a 'since the carbon nanotube film includes a plurality of carbon nanotubes' so that the carbon nanotube film has good electrical conductivity' The carbon nanotube film can replace the transparent electrode layer in the prior art to conduct electricity. Therefore, when the liquid crystal display panel of the embodiment adopts an alignment layer containing a carbon nanotube film, the transparent electrode layer is not required to be added, so that the liquid crystal display panel has a thin thickness, which simplifies the structure and manufacturing cost of the liquid crystal display. Improve backlight utilization and improve display quality. Second, the carbon nanotube film is disposed on the substrate without mechanical brushing or other treatment, and does not generate static electricity and dust, so that the liquid crystal display has a better alignment quality. Thirdly, covering a fixed layer on the surface of the carbon nanotube thin crucible, the carbon nanotube film used as the alignment layer can not fall off when it is in contact with the liquid crystal material for a long time, thereby making the liquid crystal The display has a good alignment quality.
